A sad day indeed and just wanted to add my bit for posterity.
I had the huge great fortune of working on the Jaguar flight trials team at Warton, 71-74 and managed or "ran" the trials on E02 (engines) and S1/Xx108 and B1/XX136, I was the last guy to land safely in the back seat of 136!!
I have the most wonderful memories of those times (reflected in my web site!!) and still know some of the people involved back then. It is very sad to see "my plane" go out of service, even if it is after a wonderful 33 years, and I wish all concerned with 6 Squadron today the very best of fortune in whatever comes next.
