Some years ago a very good friend of mine was killed in a Bulldog spinning accident, the aircraft belonged to a UAS based at RAF Abindon. Coincidentally, another, more senior, good friend was a member of the BOI. During the Board of Inquiry a representative from Boscombe Down gave evidence to the effect that the spinning characteristics of the Bulldog were well understood and that it was accepted (by Boscombe)that the aircraft would, from time to time and for no apparent reason, enter an unrecoverable spin. However, since the incidence of this unrecoverable spin was so rare, it was considered that it was an acceptable hazard.
This information was, of course, not communicated to we poor QFIs who were required, as part of our SCT, to deliberately carry out one high rotational spin per month. It is hardly surprising, therefore, that anyone involved with Bulldog spin testing at Boscombe Down is held in the utmost contempt by the majority of Bulldog pilots.
