Boscombe Down's reason for stopping flight tests on the Chinook Mk 2
Brian,
Wasn't it rather more specific than that? My understanding from this thread is that they were concerned about malfunctioning of the FADEC. From what subsequently came out of previous incidents (but perhaps not known to the RAF at the time of the Mull of Kintyre disaster) it was clear that the FADEC had such high authority that if it malfunctioned, it could take away control of the aircraft from the pilots. So, whatever the pilots may then have done in their entirely reasonable attempts to maintain control of a misbehaving aircraft, the FADEC could override them.
Gross negligence?? Good God no!
