The idea for Catch-22 was based on Joseph Heller's personal experience in World War II. The feelings that Yossarian and the other bomber crew felt were taken directly from problems he suffered while on duty. Heller flew 60 bombing missions from May to October in 1944. Heller was able to make it out of the war, but it took until 1953 before he could start writing about it. For this reason, the book contains references to post World War II phenomena like IBM computers and loyalty oaths. The war experience turned Heller into a "tortured, funny, deeply peculiar human being".
