heli 1
If my memory for registrations serves me correctly, G-AODA was the last 55 to fly with Bristows, she was flying for British Aerospace (or whatever they are called now), on development of the Brimstone Missile, and was cleared by the CAA for operations below 500 ft.
She came straight back from the desert somewhere, and went straight on that operation, without a major check, so there was some criticism from BA engineers in the hangar where she was parked, I got her flown back to Redhill to have some of the loose rivets knocked in over a weekends work.
There was a strange hierarchy at B/Aerospace where there were about five different canteens, and you used the one according to your pay grade, so after a morning doing a check one, up to my neck in grease, oil and exhaust grime, I would have to have lunch with the lower middle mangers.
