12. Lockheed C-5A Galaxy. Four generations of Lockheed transports were on the Pennsylvania Air National Guard ramp at Harrisburg International Airport in Middletown, Pennsylvania, in this photo taken on 17 April, sometime in the early 1970s (the photo caption didn’t specify a year). The lineup consisted of a C-121 Constellation, C-130E Hercules, C-141A StarLifter, C-5A Galaxy, and another C-121. Considering the unit was designated the 193rd Tactical Electronic Warfare Group at the time, the aircraft on the ends were most likely EC-121S airborne radio/TV broadcast platforms modified for the Coronet Solo (later Commando Solo) psychological warfare mission. Now designated as the 193rd Special Operations Wing, the unit’s mission was only partially declassified in 1989. Today, the 193rd SOW flies the EC-130J Commando Solo II broadcast platform.

8. Convair NB-36H. The NB-36H (originally designated XB-36H) Crusader was used in the studies and testing of an airborne nuclear reactor. The reactor carried aloft was not to be used for aircraft propulsion but primarily for determining many unknown factors pertaining to the effects of nuclear reaction. The NB-36H (US Air Force serial number 51-5712), featured a lead-lined flight deck and windows that were ten-to-twelve inches thick to reduce the potential radiation hazard, was flown forty-seven times between September 1955 and March 1957, accumulating 215 hours of flight time, during eighty-nine of which the reactor was operated. The aircraft was scrapped in 1958.

2. Douglas C-74 Globemaster. The Globemaster was developed after the Japanese attack on Pearl Harbor. The long distances across the Atlantic, and especially the Pacific Ocean to the combat areas indicated a need for a transoceanic heavy-lift military transport aircraft. Douglas Aircraft Company responded in 1942 with a giant four-engined design. Development and production modifications issues with the aircraft caused the first flight to be delayed until 5 September 1945, and production was limited to 14 aircraft after the production contract was canceled after V-J Day.
