RI,
Anyone with the understanding of statistics and probability reflected in your posts on this thread should consider avoiding the use of those terms in a public forum. The point of the analogy, which you clearly missed, was that the events described by the woman in her sacrament meeting story made it ridiculous on its face to the point that one need not worry about the absence of information contained in the unavailable national security data base in deciding to discount it.
DrW, anyone with the understanding of basic reasoning reflected in your posts on this thread should consider avoiding reasoning in a public forum.
I have pointed out your basic error in reasoning a number of times in this thread. And never once have you addressed the substance of what I have said. Not. One. Time. You have ignored, changed the subject, or, as in this case, deflected. So, how many opportunities should I give you to defend your poor reasoning before I conclude that you know you can't, yet you continue to do it and mislead the people on this board who are relying on you? Does Nelson being a lying bastard magically transmute non-evidence into evidence?
DrW wrote:To those familiar with aviation, including air traffic control procedures, aviation communications and aircraft performance, Russell M. Nelson’s story is ridiculous on its face. The reasons why have been described in excruciating detail.
If what you mean by "Russell M. Nelson's story" is including every single detail of every single version ever told, that's what I said at the beginning of this thread. I don't need to have any expertise in aviation or with aircraft to know that, given the nature of the event, the passage of time, and repeated tellings with different details in different versions, some added decades after the time of the alleged events, the probability of every single one being accurate is so close to zero it's not worth considering. So, if you are so confident that the story is ridiculous on its face, why spend so much time cosplaying investigator?
But, learning that you considered the story ridiculous on its face, goes a long ways toward explaining the motivated reasoning and confirmation bias I've seen.
DrW wrote:Checking the accident and incident data bases for evidence that supports the story should be done, of course. However, the absence of any mention of the events described by Russell M. Nelson in the aviation accidents and incidents data base should not be of concern in deciding to discount the story. Lack of contradictory evidence is to be expected if the story was pure fantasy.
Now that really takes a pair of brass ones, DrW, because you are
the guy who has been claiming that the absence of events in databases not only discounts the story, but proves it's all made up. You not only moved the goalpost here. You moved it to the other team's end zone. I've really been reluctant to do this, but let's roll the videotape:
DrW wrote:
Dr. Moore, Your website is a great find. Looks like the Holy Grail of aviation accident and incident information to me. No need to be concerned about entering the wrong search parameters. After entering the time interval for the search, just leave the other parameter values alone and designate the State of Utah.
Searching only the date and state parameters settings, one can see every FAA aviation accident and incident report in the State of Utah for a given year or other time interval. I did the search for 1976.
FAA Accidents and Incidents Query
Occurrence date from equal 1976-01-01
Occurrence date to equal 1977-01-01
Accident state code equal UT
It took less than ten minutes to carefully evaluate the 54 returns for viable aircraft type (there were only 7) and then to check the details of each event. Details on each clearly ruled them out as possibly being involved in the Nelson story.
So, as far as I'm concerned, this FAA listing provides incontrovertible evidence against such an incident as described by Nelson in 1976.
viewtopic.php?p=17586#p17586
That was you, searching a database, not finding what you are looking for, and declaring your failure to find what you are looking for "incontrovertible evidence."
Except it wasn't even evidence at all. Why not? Because
there are no records at all for the year 1976 in the FAA database.
What you did here is an error in basic reasoning. To reach any conclusion from the absence of evidence, whether from an electronic database or in paper records, requires two steps: (1) Have an evidence-based reason for believing that the general type of record you are looking for is in the place you are looking. (2) Look. You skipped step 1. Fatal error. You might as well have run your search in a database of dog breeds.
I called the error to your attention. "I spent a fair amount of time checking out that website to try and understand exactly what I was looking at. So, I'm going to give you my understanding and ask you to double check me."
viewtopic.php?p=17592#p17592
You didn't "double check me." In fact, you completely ignored the whole issue and changed the subject to a discussion of federal regulations and a brand new search in a completely different database.

Back to the videotape:
DrW wrote:To the list of reasons noted above as to why such an incident as Nelson described would not have escaped the attention of the FAA ,one can add:
- The pilot of an aircraft experiencing a fire that disabled the engine would declare an emergency to ATC.
- If nothing else, this action would initiate a requirement for FAA paperwork galore when the pilot landed.
- ATC would notify the FSS at the destination airport in case emergency assistance was required when the aircraft landed.
- The FAA would be notified via the FSS when the aircraft was overdue according to its flight plan, accounting for reported fuel on board.
- Even if the aircraft arrived on time and the flight plan was not properly closed the FSS would take note.
- If the plane was forced down in a field, and was unable to communicate with ATC or any nearby airport tower, and therefore could not respond to radio calls from ATC or the tower, the FAA would have been notified.
- The aircraft owner (in this case assume SkyWest) would record the Emergency Declaration event at its flight operations center and make said record available to FAA inspectors, or NTSB investigators, if requested.
- The aircraft owner (SkyWest?) would be required keep a record of any repairs made to the aircraft in the company maintenance logs, also subject to FAA inspection.
- Major repairs would require a test flight to confirm airworthiness, before the aircraft could return to service, which would also be recorded as such in the maintenance records of the aircraft.
What affect contemporary media coverage would have had on public awareness of the harrowing aviation accident can only be imagined, but it would not have been zero - which is what seems to be the case for Nelson's story.
By now it is abundantly clear that Nelson made the whole thing up and got trapped in his lies, both in his speeches and in print, by the advent of the internet. He should print a retraction and make a public apology. Given his past behavior, it is more likely the he will double down and the story will continue to evolve.
viewtopic.php?p=17661#p17661
This is an example, not with a electronic database, but with paper records. The steps are the same: (1) Have an evidence-based reason for believing that the general type of record you are looking for is in the place you are looking. (2) Look.
In the case of this mountain of paper you claim should exist, you never lifted a finger to try and determine whether 45 year-old records of this type still exist anywhere today and, if they do, where they are. And, other than some Google searches, you never tried to find them. Unless you do the work, you can't draw any conclusions from the fact that mountains of paperwork haven't magically appeared on your desk.
Back to the videotape:
At a later point, I described which records were contained in the FAA and NTSB databases according to the FAA and the NTSB:
Res Ipsa wrote:The problem is what is in the databases. The databases themselves tell us what is in them.
FAA Accident and Incident Database (AIDS): no records of accident or incidents before 1978.
NTSB Accident database: no images of original records during the decade of the 1970s. NTSB personnel prepared summaries of final reports (all include probable cause determinations) of all accidents and "selected incidents." A search of all records from Utah during the entire decade generates 55 or 56 accidents and only a single incident -- an incapacitated pilot on a commercial passenger jet. Given the disparity between the number of accidents and the number of "selected incidents," as well as the nature of the single incident (commercial passenger jet), there is no basis for assuming that database is complete enough to draw conclusions from the absence of a record for some other incident.
If any aircraft sustained an engine fire that was limited to the engine, followed by a safe landing with no injuries (just like the example you posted upthread) at any time during the 1970s, we could not find it in either database because neither includes all incidents for that time period.
You responded:
DrW wrote:Images below are (1) Items 1-10 from the 1973 list of Incidents and accidents reported in Utah, and (2) example of the detail data available for each listing. Overall this data base includes close to 400 entries (not 55 or 56), for incidents and accidents reported in Utah from 1973 through 1979. (Note the image header on the first screenshot.) A few of these reports are repeats. The NTSB version of this list is comprised of essentially the same entries for the years 1973 to 1979.
Upthread I offered to copy these and post them as a favor to RI. He did not seem interested. After again seeing RI's claim regarding unavailability of these records before 1978, I thought it best to post at least two screenshots from several days ago.
...
Each report allows access to the details, by clicking on the Details, as shown in the second screenshot below. These records were scraped and digitized and are available on the internet from 1973 on. The only Navajo (PA31) incident I saw anywhere near Cedar City was for a minor incident on the ground. It did not occur in 1976.
viewtopic.php?f=4&t=709&start=400
Except, that you were completely wrong about what you were looking at. You continued to use a third-party website that scraped information from the FAA and NTSB websites instead of using the primary sources. As a result, your description of the data you were looking at was completely wrong. First, despite its title, the FAA database includes only incidents. And it does not contain any records before 1978. The FAA states both of these facts in its explanation of the data that is included in its database. And I pointed out to you the first time around with the FAA database that it started in 1978.
You should have recognized from the fact you got the same list by searching both the FAA database and the NTSB database that something was wrong.
So, once again you searched a database, found nothing, and drew conclusions. But you skipped the step of having an evidence-based reason for concluding that what you were looking for (incident reports from 1976) could be found in the place you were looking (a database that had no records at all for 1976.) And the evidence -- the FAA and NTSB's own descriptions of what was in their database -- was right at your fingertips.
If you look at the next few entries, you'll see that a couple of the good folks here accepted what you had to say at face value when, in fact, you hadn't added anything that we already didn't know from searching the NTSB database -- that if anything happened to a plane on which Nelson was flying in Utah in 1976, it wasn't an accident. One was ready to start calling journalists.
Again, I responded to the incorrect conclusions with a very detailed post, which ended:
Res Ipsa wrote:The bottom line: If whatever happened on Nelson's aircraft occurred before 1978 and was categorized as an "incident," we know that the chance of finding that event in the online databases is exactly zero before we ever run a query. That's not because an incident didn't happen. It's because the databases do not include reports of "incidents" for that timeframe.
Confirming my understanding of the database requires doing some research and reading, as well as running several different queries to test what type of documents are included for which years. Falsifying my understanding should be easy peasy. Post a list of the aircraft incidents in Utah before 1978 from the database, and the search parameters you used to find it. DrW's single record from 1979 does not falsify my description, which applies to incidents before 1978.
My goal from the beginning has been to have an accurate understanding. If I'm wrong, I want to know that, so that I can fix my understanding. I asked DrW to do this nine days ago. He has yet to provide a single counterexample.
viewtopic.php?p=18457#p18457
After hearing nothing for a while, I asked again:
Res Ipsa wrote:DrW, can you, or can you not, use the Aviation DB database to generate a list of aircraft incidents in Utah for the years 1973 through 1977? If so, please post a screen shot.

You responded:
viewtopic.php?p=18646#p18646
Except, all that you did was use the same problemmatic third-party database instead of going to the FAA or NTSB databases themselves that were the source of the data. Once again failing step 1.
I responded by, not only pointing out that you were still wrong in your description of the databases, but described exactly how you could test the database yourself, which would have allowed you to do step 1:
Res Ipsa wrote:Every entry in your image is an accident, not an incident. I know. I looked. They all report "substantial damage." Now, rerun your search changing the search parameter to Incidents -- Commercial Aviation and then Incidents - General Aviation. Please report the total number of hits for each. If, as you keep claiming, the database includes reports of incidents dating back to 1973, each of those searches should generate a list of incidents, which we can verify by looking at the entries. And you should be able to screenshot examples of records of incidents that occurred from 1973 through 1977.
Please return and report.
viewtopic.php?p=18650#p18650
Even though other posters did try to test the database, and were unable to find any "incidents" before 1978, you did not test the database to verify what it included. Instead, you took a screenshot of what you insisted was an "incident" from 1973. Except, the report identified the event as "General Aviation Accident."
viewtopic.php?p=18667#p18667
So, still failing step 1 after pages and pages and pages. And the question is critical because if you were correct, we'd have a complete set of the data that we need in a searchable online database, eliminating the need for hunting down paper records. So, I tried again:
Res Ipsa wrote:Doc, I've asked multiple times for something that would either confirm or refute my description of what's in the database. My specific claim that you take issue with is that it does not include incidents from 1973 through 1978. I've asked you to provide a list of, or specific records for, incidents from 1973 through 1977. If those documents are contained in the database, you could retrieve them in a minute or two.
So far, you've shown me:
1. A list of accidents from 1973.
2. A report of an incident from 1979
and now, an accident report from 1973. It says right on the form. GENERAL AVIATION ACCIDENT. It lists the damage as "substantial."
It's a very simple request to test which reports are in the data and which are not. I'm not interested in your arguments about the nature of accidents. You've been claim that the relevant incident reports are in the database since a week ago Friday.
True or False: the database you are searching does not contain any reports of incidents in Utah for the years 1973-1977.
And if the answer is false, provide a screenshot of the evidence.
viewtopic.php?p=18672#p18672
You didn't respond to me, but you gave a lengthy and incorrect explanation of the same search and the same set of "accidents" that you insisted were "incidents" in a response to Dr. Moore. In it, you tried to rationalize away the fact that the records themselves stated that they were "accidents" when you were sure at least some of them were incidents. (Because, I guess, "horse" can mean "tapir")
DrW wrote:As I have tried to explain several times, when one searches the data base with NO RESTRICTIONS, the data base returns every record for the time span included. What you found is a data base that was transcribed and from the hardcopy records over several years (looks like 2005 to 2012 perhaps). The records from 1973 to sometime in the early 1980s were transcribed and digitized using a standard format.
The data base format was set up with a single field to categorize the event in question. That field was Accident Type. As I have just described upthread, whether the event was a ground loop, a hard landing, a prop strike, or a total demolition of the aircraft, a notation was made in the Accident Type cell.
There is no incident cell in the Table.
If one wants to see what happened in Utah civil aviation in 1976, enter 1976-01-01 to 1977-01-01 for the date span, and UTAH in the State field, and run the query. (Leave every other field in default.) I just ran it again and for 1976 and 54 records came up. Nothing even remotely related to Russell M. Nelson's story in any way came up for 1976. Click the Details on any records of interest to see the information as shown below.

viewtopic.php?p=18707#p18707
So, now, according to you, we couldn't tell accidents from incidents in the earlier period because incidents and accidents were both classified as "accidents." Except they weren't. I responded by showing you a record from 1970 in the NTSB database that clearly states: CLASSIFIED AS INCIDENT.
viewtopic.php?p=18719#p18719 The NTSB database contains exactly what the NTSB says it does for the years before 1982 -- all accidents and selected incidents.
Post after post after post after post because you simply refused to take step 1 seriously. All you had to do was go to the FAA and NTSB websites and read their own description of what is in their databases. Or just test the database you were using like I and other posters did. Because you didn't take the time to understand the contents of the databases you were searching, you drew incorrect conclusions from your failure to find something in a search again, and again, and again.
And then there is this:
DrW wrote:I do not know what was done before or after 1978 in terms of record keeping or destruction of records according to policy.
Again, the use of the Accident Type cell to categorize the events does not mean that they were categorized by the FAA or the NTSB as accidents. The transcribers could just as well have labelled the cell Mishap Type. As I mentioned, in this data base one sees everything from hard landing to a runway collision to aircraft demolished.
This data base (FAA and NTSB versions) were transcribed from hardcopy records and they happened to use the Table format you see. These are not the original official records, and do not claim to be. They are a convenient and accessible way to get to transcriptions of official records starting in 1973.
With a fairly consistent average number of entries per year, and pretty much the kind of aviation events one would expect to see in Utah, I would be very surprised if the curator decided that an in-flight fire on a commercial flight, with a forced landing in a farmers field, didn't rate inclusion, especially when two hard landings did.
My view is that the Russell M. Nelson story has little, if any, basis in fact (except possibly on movie screens). And if it did, the embellishments that appear in the later versions of the story certainly cross the line. This view comes from operating aircraft in controlled airspace, according to a flight plan, and understanding the close eye that ATC keeps on aircraft with radar transponders.
It comes from knowing how serious the FAA and the NTSB considers in-flight engine fires and forced landings, especially of commercial aircraft, and especially on civilian property, to be. The number and types of alerts and notifications that would have promulgated through the ATC and NTSB systems had such an event occurred do not magically disappear from all the places they would have been recorded. All this is not to mention the human interest story that the pilot, Russell M. Nelson and the other passengers would have had to tell.
Yet, nothing.
The juxtaposition of two sentences from that post is a crystal clear illustration of the basic error in reasoning you keep making over and over:
DrW wrote:I do not know what was done before or after 1978 in terms of record keeping or destruction of records according to policy.
DrW wrote: The number and types of alerts and notifications that would have promulgated through the ATC and NTSB systems had such an event occurred do not magically disappear from all the places they would have been recorded.
The first sentence completely negates the claim of the second. Disappearance of records doesn't happen by magic -- it happens through policies of record keeping or destruction, which you just said you know nothing about.
If you know nothing about the policies regarding record retention and destruction, then you have no evidence-based reason to expect that all the records you describe in the second sentence still exist today.
The same problem repeated over and over. Failing to have an evidence-based reason for why you expect to find what you are looking for in the place you are looking. You just assumed that every record that was created would exist today. And then you said "nothing" without ever trying to look.
And finally, the most recent skipping of step 1.
DrW wrote:The Bureau of Aircraft Accident Archives <
https://www.baaa-acro.com/ > maintains a searchable data base that archives aircraft accidents worldwide by date, aircraft type, registration, operator, region, and number of fatalities, if any, along with other search parameters. Details and narratives from NTSB notifications, or other official accident reports, are included in a Details section.
...
Had the events Russell M. Nelson described actually occurred, the resulting NTSB notifications would have appeared in the
www.baaa-acro.com data base. The only accidents reported for SkyWest were the three listed above.
Except, there's absolutely no evidence based reason to make that claim. First, you talk about "NTSB notifications." For all the searching folks have done, no one has produced a single piece of paper that is a "NTSB notification" from 1976. Based on our FOIA requests, it appears that NTSB notifications were destroyed and not retained as permanent documents. There is no evidence-based reason to expect that this "Bureau," which is in reality one guy in Geneva who is compiling a database, has any "NTSB Notifications" from 1976, let alone a complete enough set of such notices that would allow us to draw a justifiable inference from the absence of a notice that matched Nelson's report.
But it's easy to confirm that the "Bureau's" database does include reports from the NTSB, and we do have those in a database. So it's pretty easy to test the percentage of NTSB Reports (as reported by the NTSB) that appear in the Bureau's database. And the answer to that is around 2% So, your statement "Had the events Russell M. Nelson described actually occurred, the resulting NTSB notifications would have appeared in the
www.baaa-acro.com data base" is completely false. What's true? Had the events that Russell M. Nelson described actually occurred, there is a 2% chance that we could find it in this database.
Same mistake. Again. Skipping step 1: you never bothered to look to see how complete your database was before you searched. You just searched, and then unjustifiably jumped to a totally false conclusion.
That Nelson's story may be facially ridiculous does not give you license to ignore basic logic and principles of reasoning. If there isn't sufficient evidence to disprove the story, tough luck. It's a 45 year old case. Documents are destroyed. Witnesses die. Recollections become more inaccurate and fade over time. That's just reality. Sometimes the evidence just isn't there to prove the case you want to argue.
If you're going to argue from the absence of evidence, just do it right. Half-assing it gets you exactly what you've done throughout this thread -- make terrible inferences that are easily shown to be flat wrong.
DrW wrote: That said, if you believe that one needs to comb through thousands of reported incidents such as cabin pressurization issues, bird strikes, blown tire on landing, landing gear deployment issues, temporary engine failure, loud bang when the landing gear was deployed, (false) in flight engine fire indication in the cockpit, lavatory smoke indication, wingtip strike on landing, landing gear indicator disagreement, flaps deployment issue, indication of thrust reverser deployment in flight, runway excursion on landing, deployment of air driven generator in flight, overheated brakes, etc., have at it.
Here is a URL address where you can find incident reports for SkyWest:
https://www.aeroinside.com/airline/skywest-airlines. It may not go back as far as 1976. However, it does include the kinds of routine incidents that you would find should you get access to the incident records from that year. Let us know if you make it past the first 100 reports.
Now you're starting to understand what it takes sometimes to be able to reach a conclusion from the absence of evidence. You have to roll up your sleeves and do what it takes. And if it takes trawling through thousands of records, that's exactly what you have to do. And if you're not willing to do the work required to draw conclusions from the absence of evidence, then what you say is "There isn't enough evidence to determine what did and did not happen." Because that's the 100% true and honest answer if you aren't willing to do the work.
by the way, the link is to 156 reports. I could do that before breakfast. I'm not going to, because a small selection of incident reports from the last three years doesn't help me figure out what did and did not happen in 1976.
