I have been flying the -17 for nine months and I have about 600 hrs in the jet so far. However I most likely will only get 100 more if that in the next three months due to me being required to focus on my "office job" and not flying trips. My guess is C-5 guys get more hours than C-17 guys because currently they do not have to stop flying in order to spin down for a deployment or spin up after one. Their trips are all long ones with no Airdrop requirement as well and often run past their scheduled return time. New Guard and Reserve guys can probably get the most because they can guard bum and pick up as many trips they want while seasoning. On active duty now a days flying is only part of what you're judged on, with how good you are in the office, how many awards you win, how much you're educating yourself etc. From my understanding, the reserves don't have to deal with that.
