Ahhhh the Wessex!
I suppose time dulls the memory, only leaving the good bits, but I loved the thing. All the frights were self induced, (one JFR induced!) except the time I extended a training sortie at Merryfield so as to return to VL with 300lbs MLA fuel, only to have both engines flame out as I taxied onto stand. So much for the gauges!
For Lu Z, I beleive the Gnome was a license built T58 anyway, so we even pinched that from the septics. I was always amazed that the US services stuck to the pistons for so long.
Delivered a few to Lee-on-Solent at the end of their lives, and see one now and again (XT770) in a paint ball park a couple of miles from here. A paint ball park indeed, and repainted in pseudo camouflage. Yuk.
