I do think there’s a drip-drip-drip aspect to the falsehoods shown throughout this crash. One plane occupant after the other shows himself (or herself) to be a compromised witness, telling untruths about things that are dispassionately discernable as being otherwise, even provably so.
The life jacket may be important,it may be adult I don't know yet. But what is more important so far in my research is that an excellent case has been made that the pilot was lying his ass off and could have made a landing at a nearby air strip according to the elevation and air speed.
