When a plane crash occurs, usually there are hundreds of bits of plane shattered everywhere. I watch shows like “Air Disasters”, but they never explain how they know the “right wing flap came apart mid air” or know how the “fan blade dislodged on impact and not in the air”?

I participated in 1 investigation (air to air collision). I am an expert in avionics. The investigators recovered the data from several units and gave them to me for analysis.
The primary question in front of me was “when did x unit fail?” and “could that failure have caused the collision?” From the hexidecimal data put in front of me, I was able to determine that the equipment was still functioning (and recording) correctly at the time of impact.
This (along with other data from other experts) led the investigation to conclude that it was a matter of pilot error.
