Companies that I have flown with will spend 50-100 hours with you before you do fly the line
Did you do an endorsement on the Space Shuttle?
From my very limited experience in this area ...
I suggest it is 'very limited' experience.
If you don't know what the difference between an endorsement, line training and flying the line is, and you think 50-100 hours is space shuttle stuff I'd hate to see you go work for REX
