The C64 version was written from scratch in 2 weeks. This is because two rookie programmers spent 6 months working on a version which was flawed from the start, using a hardware routine which made it look impressive but move very little. With no help from senior programmers, and an atmosphere of racial abuse, a quality product was never likely. Despite this, Zzap! magazine reviewed this first version, which was nowhere near completion, and gave it a very good review. One of the original programmers claimed that the review was bought in exchange for exclusive coverage of forthcoming Ocean games, but the reviewer in questions claims that he'd remember this if it were true.
As well as the obvious 9/11 parallel of Arab terrorists hijacking planes, the plot is spookily close to the Lockerbie tragedy of 1988, in which Pan-Am flight 103 (just 1 number away from the plane in the game) was blown up over the Scottish town of Lockerbie. Lybian agents were responsible - which probably explains the change Black Wolf mentions.
