They are the reason for my wife's fear of flying. Engine blew up on t/o at Dhahran, aircraft evacuated. Passemgers were totally abandoned by the airline ('we have another aircraft coming through in two days'). The Saudis didn't want to know - couldn't leave airside, couldn't change money, couldn't phone. They camped in the departure lounge for about 24 hours before the British Consul somehow got to hear about it and sorted it sharpish - Gulf Air rescued them.
