When I was but a newbie ULAS stude, one of our QFIs (Malcolm Sw*****) used to harp on about how 'fee-no-meenal' the PR9 was when he'd flown it a couple of years earlier.
That was back in 1970. Amazing that it was still flying 36 years later and 3 years after I retired!
BŁoody shame there's nothing to replace it. 'Capability holiday' my ar$e - just another gap in our underfunded armed forces.....
