20,000 to 30,000 hours ex concorde etc doesn't qualify you to train. And I also agree that 1500 hrs on a particular type doesn't either. For the high time guy all that equates to is that you have 20,000 or 30,000 hours worth of flight time; but it doesn't mean you can train. Some people seem to make a prerequisit for a trainer to have 'x' amount of hours. Bollocks. Some of the worst instructors I have ever came across are some of the most 'experienced' operators/pilots that I have met. They may know one or two things about an aeroplane, however their idea of teaching is bawling at some laddie in order to scare him into submission. Training is about finding the right type of person with the right type of mentality. It isn't about being so sort of Chuck Yaeger sky god, with multiple type experience; all within a legacy carrier!
However blackred, I'm sure you are a fine pilot. You will have been trained by the best, certainly.
