When Major Gus Denver is introduced in the episode "Appointment at Liege" he is mourning about his crew being killed (while he was on temporary stateside duty) over Liege, Belgium. In THIS episode 'V for Vendetta' he is talking about his crew being killed over Mannheim Germany.
General Savage says he'll fly Major Denver's plane because his is being worked on. But when he looks back at Major Denver after they've lost General Hoagland in the parachute jump, the name on the plane is General Savage's Piccadilly Lily.
