I was reminded of this after the "best crash sequence" thread which mentions a film called "White Nights", where a 747 has an electrical fire over the Soviet Union and has to make a crash landing. If a western airliner got into trouble and had to land somewhere like mid-Cold War USSR, I don't think there would have been a problem.
There have been a few cases of planes being hijacked to so-called enemy countries, an Iran Airtours 707 was hijacked to Tel Aviv a few years ago - I must say that when the destination was revealed to the passengers (all Iranian) there must have been some brown trousers. In fact the Israelis treated them with great hospitality and they were flown straight home (except for two who took their chance and emigrated to the US). That TWA 727 that was hijacked by Amal to Beirut in 85 was slightly more problematic, given that the hostages were taken to the Beirut suburbs and held for a week or two, but again, I understand that they were well-treated and were taken most evenings to the Summerlands Hotel for dinner, one of the most luxurious in the eastern Med (what a bizarre sight anywhere else in the world, a bunch of westerners being marched at gunpoint into the hotel's posh dining room in full view of the western press corps staying there, then back to their basement). The passengers on the Korean Air 707 that was shot down by the Soviets and crashed on a frozen lake were released pretty much immediately, weren't they?
My point being, has there ever been a case where airline passengers have been hijacked (or though other circumstances deposited) to a dangerous or hostile location and run into difficulty (not counting the US Navy diver who was shot in the TWA hijacking for being part of the same military that had bombed the hijacker's home town only months previously)?
