HC Deb 14 February 1986 vol 91 c567W
Mr. Marlow

asked the Secretary of State for the Home Department whether employees of E1-A1 are permitted to remove their weapons from their aircraft at Heathrow.

Mr. Giles Shaw

Firearms which are carried on board an aircraft for security purposes are required to be surrendered to the police or customs on arrival. If the aircraft is staying only a short time, the firearms are sealed in a container on board. If the aircraft is staying longer, the firearms are kept in safe custody by the police and returned shortly before it leaves.
