I very much agree with exaviator 4 points above! I believe that 2 of the most common factors in flying accidents are:
- Bad Luck
- Exuberance
A catastrophic failure is sheer bad luck.
A low level aeros maneouver that goes wrong is probably exuberance.
I saw the former at an Air Show in RSA - when the Silver Falcons jet lost a wing - then a few weeks later, a C210 performed an impromptu roll whilst departing from an Airshow at Nampula in Mozambique and struck a mud hut, killing the occupants of both the Cessna and the hut.
