I saw XM496 (Kemble) run all engines at the '98 Airshow there. But she was parked over the other side of the runway, so I could hardly hear her, and I think it was only up to ground idle. From what I remember there was an element of ground idle Tyne sound, but mainly a 'swishing' sound. It WAS due to do a taxi demo that day, but they had a brake problem.

That's the only time they've run it at Kemble Airshows.
When I went on board that Brit once, they played a video of it doing its last 'daisy cutter' flypast and then landing at Kemble. Someone needs to get hold of that.
I'm sure DD entertainment (Ithink it is) will release Buccaneer soon...hopefully.
The Brit is my favorite propliner!
