Lying to investigators and destroying evidence is unquestionably wrongdoing, and required far more explicit intent and action than merely failing to correctly fly an aircraft.
Nobody was in it when it crashed, he jumped out of the plane midair.
“Failing to correctly fly an aircraft” is quite an understatement. This person didn’t just accidentally run out of fuel, or accidentally stalled.
He intentionally set up the airplane with cameras, intentionally wore a parachute, intentionally stopped the engine mid-flight and then intentionally jumped out of the airplane while holding a camera on a selfie stick.
None of this can be described as ”failing to correctly fly an aircraft”. What he did required explicit intent.
