I was not flying in the 90s but I know people who have and the only issue I have with this total time required back then compared to now is the opportunities available. In the time it takes to get 1500 hours today for the average pilot, they probably could have got 3000hrs in the same time. Other than pilot mill CFI jobs, entry level pt. 91 and 135 gigs are getting harder and harder to find these days. Aviation is about luck and timing. These days it's more luck than anything else. Good luck finding a kid with 500hrs multi these days.
