It's always wound me up that pilots abilites are measured by hours ..
It's BS and for you to suggest that a 700hr 330 driver is any less competent than a 2000 guy is simply madness.
We've all met high hour hopeless cases and low hour aces.
Give me a 700hr enthused, conscientious keen to learn guy every day over a high hour guy who can't be arsed.
It the companies (high level management) fault this mess, not any individuals who are at the coal face.
Ps
Concorde wasn't a popular fleet in BA. Dozens if not hundreds of guys could have flown it from a senior point of view. It was effectively short haul with little variety and very low on allowances compared with the 744.
For every real pilot who was really passionate about it there were a whole bunch of guys who were simply keen to say they flew Concorde because of the ego - and why not...
