During the troubles in Northern Ireland, all British Airways Domestic flights to Belfast were classed as top security. Scanners and X-Ray machines were not used on these flights. All heavy and hand luggage was hand searched in front of the passenger. Plastic bags containing foods and cakes etc were all binned. Every passenger was then Frisked and if given the all clear he/she was allowed to pass through the airside gate. Even the captain who would be flying the aircraft was Frisked.
