"...A reviewing Naval officer said, "It is important to note that the air bubble created by the closed canopy undoubtedly saved the pilot from the extremely harmful compressibility effects of the ejection seat cartridge explosion." MacFarlane's [Wyvern Pilot] comment after recovery was a masterful understatement: "I was in a highly nervous state, for catapulting is a very startling experience."
