Yes, I know quite well. In fact, the story of how Zucker found Zero Hour is kind of famous:
From wikipedia: "The ZAZ came to the idea of spoofing airplane disaster films when they accidentally taped the 1957 film Zero Hour!, while they were looking for commercials to spoof.[2"> Abrahams later described Zero Hour! as "... the serious version of Airplane!"."
