"When I was a kid the Army used to use the strip occassionally with DHC Beaver aircraft and approximately once a year a Harrier would land there I presume to show off to the new recruits of REME at Gibraltar Barracks."
It's not been used in years but was the haunt of the Beaver then! These days it's just for the REME only, with no flying, just tanks and building.
Hope this is useful!
