I believe the hon. Member is referring to BA flight 149 to Kuala Lumpur via Kuwait, which landed in Kuwait on 2 August 1990.
The previous Government have previously outlined the facts of this flight to the House through the then Prime Minister's (right hon. Baroness Thatcher) statement on 6 September 1990, Official Report, columns 734-43. In any case, it is the long-standing policy of the Government not to comment on operational intelligence matters or the activities of UK special forces.
