The Human Torch flies through space at one point, aflame. This is impossible, however, as he needs to be surrounded by oxygen to flame on, and there's no oxygen in outer space.
Based on "The Coming Of Galactus!", "If This Be Doomsday!" & "The Startling Saga Of The Silver Surfer!" from Fantastic Four #48-50 (March 1966-May 1966), written by Stan Lee, art by Jack Kirby.
