"Round Engines" — a tribute page circulated among Skyraider veterans, celebrating the radial piston engines that powered the Douglas A-1 Skyraider through its long service in Southeast Asia. Radial "round" engines, epitomized by the Wright R-3350 in the A-1, were prized by pilots and maintainers alike for their distinctive sound, smell, and hands-on starting ritual — a stark contrast to the cleaner but less characterful turbine engines that eventually replaced them.
