Pan Am also recognized the ground breaking work done by Hank Ransome with regards to operating into Washington National Airport by utilizing the DHC-7s unique capabilities. The DHC-7 was the only transport category aircraft to be able to operate and conduct STOL (Short Takeoff and Land) operations into Washington National's airport because of the way the airport's runways all cross at the center like an asterisk. Until Hank Ransom's efforts were approved, only one runway was capable of being utilized at a time.
