OAT...not for me!
But I did pass through there some years back, and got precisely nowhere as a result of my OAT training. 2 years of unemployment followed.
No first-time passes for me though, and a bit on the senior side, over 40 when I started the Upgrade Course. Made it, left the Groundschool due to low teaching standards, and finished ATPL Nav's myself.
OK now, though, mainly due to own efforts. And some good luck on the way. OAT is just another flight training establishment, no quirkier than others, bit arrogant, and rather costly. Forget its reputation, means little or nothing in the real world.
And good luck to all aspiring professionals. Sincerely. RH
