Plot hole: James Bond shouldn't have gotten away at the end of the airport scene, where he steals an aeroplane and pretends to be a flying instructor. He had no wings with which to fly away, and he ended back up right outside the airport. So, the henchmen, who seemed to still be chasing him one shot before he parked, should have been right on him, waiting when he got out of the plane.
Plot hole: Bond steals the ancient double decker bus, not noted for any kind of speed, and he also doesn't get much of a head start against the police, yet in later shots he's quite a distance ahead of them. Skilled driver or not, it's a bus.
Chosen answer: Bond just stored the bullet in his own mouth to hide it. As he puts it in Kananga's mouth he presumably pulls a pin, or forces Kananga to bite it.
