 The first eight-and-a-half chapters of this Commando Cody serial were lampooned before their main feature-of-the-week (only half of the ninth installment was shown, with the in-show excuse being "the film broke").In his 1984 book "In the Nick of Time" author William C. Cline dismissed the serial as a "quickie".Because of a failure to renew copyright, "Radar Men" lapsed into the public domain in 1979.
