Re: Alpha Jet
Alpha Jet - It's the nearest thing to the Hawk in performance terms
From the options on the survey maybe. It's also an entirely new aircraft to the Air Force.
Boringly, but realistically though it'll be the Hawk 128 (or Hawk T2 as the RAF call it). Arrows pilots will have trained on it, be familiar with it, the RAF already has them (along with logistics/service/parts). It's even more Hawk-like than the Alpha Jet (being a Hawk and all...).
