Many aircraft accdents result from Pilot Error - often the basic error of not leaving the thing in the hangar and going by train !..
Danny, that reminds me of the old one about the Station Flight Safety Officer, SFSO.
CO to AOC 'And this is our SFSO, Flt Lt Bloggs sir.'
AOC 'And how do you contribute to flight safety Flt Lt Bloggs?'
Bloggs 'They don't let me fly sir.'
