thanks for clarifying that it is an ATP you need and not just 1500 hours. By the time I had all the night, instrument , XC etc for my atp, I had a total of about 1700 hours...
and back in my day, the FAA went through your logbook and made sure (as well as they could) that it wasn't P51 time.
I did bank checks, instructing and all sorts of crap...I'am sure you understand
