The conversions are really well done and this is a great idea for a vignette!
A small suggestion. The scene looks kinda posed. Resist the idea of having any figure grouping look posed. If you add a photographer taking their picture the rest of the vignette would work, but otherwise give them something to do. The pilots could be looking at a map and talking together. One crew man could be handing out letters from home. Something like that and whatever works for you.
All the best,
Dan
