DO IT! Your "seniority" in flight school means nothing, and with as much delays as some guys get out of their commissioning sources, your year ahead (especially if you can work drug deals to work minimum wait times) won't mean shit. Technical degree and a year behind, which ultimately ends up not much different than your peers, especially while YGs get delayed a year or two.... TOTALLY worth it. Fuck the wickets the Navy sets. If you can get a free technical masters... GO for it. The civvy world will pay dividends for it, so might as well get as much out of the Navy as they'll get as much out of you as they can.
