Re. Gannets
OK, I flew both. The first is the A/S version, later converted to a trainer, the T5 (instructor in the 2nd cockpit), the one with the bulge is the AEW3.
Both a delight to fly, despite the AS4/T5's tendency to shake, rattle but NOT roll, I enjoyed both and was frankly grateful for the AEW3's sedate 95 knot approach to the carrier deck.
Despite being retired still fairly busy. Will post more info for those interested later (how do I insert one of my own photos? It doesn't have a URL?). Meanwhile, a US- group have restored a T5 to flying condition, just Google "Janet the Gannet".
