On the Brink: Doomsday

In the sequence about the Cuban missile crisis, the narrator says "For the first time ever, the president invoked pentagon procedures for nuclear war" while a still shot of Kennedy signing something is superimposed with footage of war preparations. Among this footage is a shot of two unusual jet fighters taking off simultaneously. These unswept low-wing planes with two engines above their wings are neither American nor Russian but in fact Canadian Avro Canada CF-100 Canucks.

The aerial color shot of the rising 'Hiroshima' mushroom cloud shown early on is actually from Nagasaki. There is no footage of the Hiroshima explosion or rising cloud due to equipment malfunction; there are only a few seconds of film showing the static Hiroshima cloud some time after the explosion.
