Continuity mistake: When the staff member at the college runs away from the bad guys to get help, and is quickly shot in the back by Voller's henchman, she falls forward on the floor, face down. Dead. But a short time later, when Indy discovers her body on the floor, he kneels down to attend to her (and looks at his hand to see her blood there), she is now lying face-up on her back.
Continuity mistake: Inside the plane, Indy looks at his bleeding wound. Note how shiny and wet it is, as opposed to an instant shot later when it looks dry.
