Lemme :
Thanks for your detailed list of qualifications. very impressive indeed . I went to visit your web/sire Blog and read some of your Tweets and likewise I was very impressed . You also seem to spend a tremendous amount of time doing this.
The first question that come to my mind is why are you doing this? Is it just a hobby or is it professionally motivated, like selling a technology or a project/ idea ? or just wanting to show what people can do with FR24/ ADS ?

The problem I have is that your presentations are using sentences like , the aircraft did this, the crew did that, ATC replied, etc.. like these were factual .
one example : quote from your blog :
The airplane initially arrived with conceivably enough fuel to complete the approach and landing safely
How do you know ?
But in fact a lot of this is taken unofficial sources like newspaper coverage, so called witnesses , You tube R/T transcripts of unknown origin , posts in forum by unknown " experts" etc..
To be fair, you do mention this in your introduction :
These observations stem from sparse ADS-B reports, an unauthorized copy of a related RJ85 Flight Crew Operations Manual, Vol 1. plus other references not known to be accurate in comparison to CP2933 airplane combined with best-intentioned judgments and helpful advice from online commentators.
But to the uniformed non aviation specialist , the end product on your blog looks very much like a serious accident investigation. And it is not. And there lies my problem . You become yourself another informed source for the uniformed . Kind of he blind leading the blind .

Another and final example to prove my point : as far as I know there is so far no real official statement coming from a bona fide source like the NTSB or the UK AAIB that this accident was due to a fuel exhaustion, and even if it really was the cause (although it looks like it was) , I personally very much doubt that the 4 engines would quit at the exact same time .But i am not an expert in RJ fuel systems . cross feeds and pumps, so I leave this part for those in the know. . Anyway all that can be very easily verified in a sim. And that is where the real accident investigation team comes in , and look at the facts.
