Nicknamed the "Flying Vacuum" because of its low slung jet intakes, the F-89
Scorpion would ingest any loose objects it crossed paths with on the runway. An
attempt to place screens over the intakes failed when, at high altitudes, ice
formed over the screens and caused the engines to flare out. Designed as an all
weather ground attack fighter, the Scorpion was the first US interceptor armed
with nuclear air-to-air missiles and the first aircraft to live fire an AIR-2
Genie nuclear air-to-air missile on 19 July 1957.
