Re ORACs post above on Bishops Court/Ulster Radar, here is a bit of history regarding the IRA attacks on RAF personnel at the base.

There were plenty of stories regarding the supposed "leniency" the IRA showed towards the base, the main one being that one of the civilian controllers had "influence" and they didn't want to **** in their own nest. This was at odds with the fact that one of civvy assistants was a corporal in the UDR, something we only discovered when she was manning a road block we were stopped at one night.
The authors line about the brightly coloured bus being discarded after the attack is a bit misleading. What I think he means is that the buses were painted in Ulsterbus livery, which fooled no-one. The bus was still in service during my time there (1974-1976) with the bullet holes in the ceiling covered over with duct tape!
