Roger Ramjet 1965 S01E01 "Dr Ivan Evilkisser" Roger Ramjet and the American Eagle Squadron

Roger Ramjet is a patriotic and highly moral — if not very bright — hero, who is typically out to save the world, with help from his Proton Energy Pills ("PEP"), which give him "the strength of twenty atom bombs for a period of twenty seconds". The world is invariably saved by defeating the various recurring criminals who populated the series. On government missions assigned by General G.I. Brassbottom, Ramjet encounters various nemeses during his missions. Typically he is caught, and must be rescued by his crew of sidekicks, the American Eagles: Yank, Doodle, Dan and Dee (a play on "Yankee Doodle dandy," which also happens to be the tune to which the theme song is set). Although his Eagles appear to be children, each of them, except for Dee, flies his own individual ramjet aircraft expertly, and they are obviously much more savvy than their leader.
