Hi all, I have just come across this thread purely by chance so have registered in the hope this information, although late, may be of use to the original poster and others.
Back in the early 70s I was a member of the flight test department at Warton working on the Jaguar project and specifically I was part of the group which managed the test aircraft - wrote the schedules, briefed the pilots etc. “My” aircraft was Jaguar E02 which had been brought over from France in 1971 and which after a programme of engine trials was used for the first phase of the two seat spinning trials in 1974, as best I recall.
My job to took me to the control tower very frequently and I certainly knew the ATCO referred to in the original post.
It is indeed a shame that the Jaguar spinning film is not on the Internet, a few years ago a fellow member of the team told me he had the original film and was going to digitise it but I've not heard from him since. The film referred to in the original post of the aircraft tumbling and with smoke all around was taken from the ground at Istres, France, and is of the preceding trials by single seat Jaguar A03. We had no ground to air photography on EO2’s flights.
All the first phase two-seat Jaguar spinning flights from Warton were conducted by deputy chief test pilot Tim Ferguson. All test pilots are very brave people but Tim must be one of the bravest of all for having conducted these trials. He was indeed told to bale out if the spin had not been recovered by a certain altitude and at least once he was told to do that and at least once he did not obey and managed to get the aircraft safely back to base. We also had an incident when the cockpit instruments showed he was low on fuel and he made an emergency landing at an RAF base. Reg Stock and Eric Bucklow were not regular Jaguar pilots at that time, IIRC.
JohnFTEng is correct, and yes, the trials took place around the Settle area, so we could get at the bits if the worst happened. The local paper once reported that a part of the aircraft’s kit did descend to earth….
I left Warton in November 74, some months after these spinning trials we completed, but well before Phase 2 started. Jaguar E02 is (the last time I looked) preserved as “E1” in Bordeaux, proof that Tim always made it home safely.
