It's funny how you conveniently leave out the other two, particularly Flight 93 which reportedly landed in such soft land that the majority of the 95% of the aircraft that was reportedly recovered was said to have been found underground. Guess those titanium and reinforced steel data recorders were much more delicate than the dna that was reportedly recovered.
(cue the eye rolls)
Flight data recorders mass about 8-10 kg, contain electronics, and are armored by a steel shell of only 6mm in thickness. It is rated for about a thousand g's shock load, duration in the millisecond range.
DNA is a molecule. As part of its preparation it is routinely subjected to extended periods of 10,000 g's or even more. As far as shock, impact, and dynamic forces are concerned, DNA is vastly tougher.
Leave the science to scientists, please?
