This incredibly popular and entertaining Republic serial has Commando Cody (George Wallace) battling evil Moon Men who want to blow up the Earth using “Lunarium”. Cody has a cool rocket pack that allows him to fly and fight off the alien menace. (It’s kinda easy when the aliens use third rate gangsters as hired thugs.) Each week he survives close calls from crashing planes, volcanoes and collapsing bridges in chapters with titles like “Molten Terror”, “Bridge of Death” and “Murder Car”.. Co-starring a pre-Lone Ranger Clayton Moore. This later was the inspiration for The Rocketeer.
