Whatever the reason for crash -
- in the "old days", most of the time, the road to an airline jet cockpit was long. Prior to landing the big airline job most pilots flew in all manner of organisations over many years. You built up a reputation in the industry/military, people knew you, a trail if you like, a history - Chief Pilots etc could get the "gen" on you pretty quickly. A "good egg", "reliable", "a good pair of hands", etc etc.
Now with £100k plus and a year or two at flight school you, with no work experience anywhere, no history, nobody knows you from a bar of soap, are welcomed into the right seat of an airline jet.
I think there many problems with this but the one that struck me most was security.
