Buck Rogers is supposed to be a Captain in the Air Force, but he is wearing Navy wings. In fact he is not even wearing Naval Aviator (pilot) wings, he is wearing Naval Flight Officer (navigator) wings.
Episode: Jennifer> When Buck is standing in the hangar, following a short protest with the security guard about boarding flight 409; the flight 'Jennifer' is on, the P.A. announces the flight take off, and calls for Captain Christopher Pike. Captain Christopher Pike was Captain James T. Kirk's predecessor in the original Star Trek pilot and opening episodes; either a strange coincidence, or possibly a homage to the classic Star Trek series.
