The Kuwait 737-200 fleet was only the 1 aircraft. It was involved in a hijack on 24/7/80 when it was forced to fly to Bahrain then Abadan, Iran and back to Kuwait. Hijackers then gave themselves up with no apparent violence or injuries. Kuwait Airways then sold the aircraft as VR-BOX in December that year.
Thankyou for that! So that narrows it down a bit ;-) It just seemed to make sense that they had more than one 737 in the fleet for short/medium haul in the M.E, so I naively swallowed the story.
