While A Yank in the R.A.F. is a decidedly uneven affair, there's enough positive about it that most viewers will probably rate it as a fairly decent, if very dated, film. Like many other such war-elated films made at the same time, Yank has a propagandistic aspect to it; in this case, it's to help convince the isolationists in America that the U.S. needed to get involved in the war overseas. It plays this angle with little subtlety, but the bigger problem for many modern viewers will be the manner in which Tyrone Power's character pursues Betty Grable's character. His relentless will be considered harassment by many viewing the film today, and it doesn't help matters that Power's character -- despite the actor's considerable charm -- is simply too much of a jerk. But there are factors that balance these flaws, among them the fact that Power and Grable possess such delightful chemistry and that both are in peak physical form. Garble also gets to entertain with a few pointless but engaging musical numbers, and the action sequences are quite gripping and very well done. The special effects work for the time is top notch, and the cinematography is very effective.
