A UFO attacks Dr. Quest's lab, taking Jonny and Hadji captive. The boys will be returned only if Dr. Quest reveals the plans of his new aircraft. Ostensibly, the aliens want to use the invention to disable the Earth's space programs -- but Quest and Race Bannon suspect that the villains are of human origin. First syndicated on September 28, 1986, as part of the "Funtastic World of Hanna Barbera" weekend package, "Aliens Among Us" was later incorporated into the standard Jonny Quest manifest, along with the "classic" episodes from 1964-1965. ~ Hal Erickson, Rovi
