Continuity mistake: While Major Allison is piloting the X-80, the style/model of the aircraft differs in shots, and two different numbers appear on its body - FC-226 and FE-229, as well as four different tail numbers that appear on its tailfin - 62216, 70236, 70229, and 61226.
Continuity mistake: After Major Allison's return, when he's in the OR with Dr. Richman he's lying shirtless on a gurney, but in Allison's closeup he's wearing a pajama top and there's a slatted headboard behind him - which is a shot taken from a later scene in his hospital room.
