If I remember correctly G-AODA was the last Whirlwind in Bristow service, it was working for British Aerospace helping to develop the Brimstone Missile. It must have been around 98, I went to the works to do a check one, and found it parked between a Hunter, and a Buccaneer, it was looking a bit sad, and was getting some criticism from BA engineers, so I advised JD to get it back to Redhill for a weekend to have some of the rivets knocked back in.
I don't know exactly what it was doing, I don't think we were allowed to know, but it was cleared by the CAA to operate at zero altitude over the missile ranges.
The missile went on to great success in Libya and Iraq, and I believe its foreign sales potential is good.
