However to get to sit in the left hand seat of a 777/747 you are looking at 15 to 20 years flying experience. It has been done in less, but not that often, and the insurers get a little twitchy I believe.
Quite so L337. And on a similar note someone who is trained in a "Part147 superstore" with the bare bones 12 months experience required to get a B1 or B2 EASA AME license is not going to become a chief engineer immediately either .
