All of this is horribly sad. Years ago there was a similar tragedy in my family and a similar official report of 'pilot error'. But my sister-in-law refused to accept that verdict.

My brother-in-law was a highly qualified and experienced pilot, it had been a clear, sunny day with only a gentle breeze when his plane flipped over on landing. He was killed along with his son and his daughter's fiance. So the tragedy devastated two families.

My sister-in-law kept asking questions and hired an investigator.

It's not that people have bad intentions, but there is a tendency on the part of some professionals - controllers, safety officials, military pilots etc, to think of amateur pilots as prone to mistakes.

In the end the official verdict was changed. It was concluded that the air traffic controllers had directed my brother-in-law to land too soon after three large airliners had used the same runway. The lingering turbulence had caused his plane to flip over. There was no pilot error.
