A silent film record of the “Putt-Putt” test vehicle built by General Atomic to prove the principle of propulsion via discrete detonations. A part of Project Orion, Putt-Putt used canisters of C4 plastic explosives rather than atomic bombs, but still managed to – eventually – lurch itself into the sky.
More on this was in issue V1N4 of Aerospace Projects Review, and more will be in my Nuclear Pulse Propulsion book.
