I don't know if anyone noticed this but in the scene after the mission breifing of escorting a 2-seater.After their out of the tent,you see a german ground crewman holding Heidamann's D.VII's tail,and the funny part.If you look closley,you see the ground crewmans Feldmutze(the visorless hats)flies off from his head from the rushing wind from the props.Bet that happened alot.
