Should be an AAIB report on BAIJ giving names as it involved fatalities but I'm blowed if I can find it.
Position of the crash was Raans Road, Amersham, Bucks, about 7 or 8 miles from Denham.
I'd flown my brother in law in this aircraft some time beforehand, plus I'd flown it solo about 2 weeks before the crash. On this latter occasion, during the pre-flight, I'd found the stall warner was apparently not working. During the flight, I tried stalling it - not a peep from the stall warner so I told the person behind the desk and entered it in the tech log when I landed.
My brother in law was a part time fireman, and was on the first appliance to arrive at the crash. He noted that both occupants were 'bent double' ie had probably not been wearing their shoulder straps (it was an Aerobat hence had 4 -point harness') then realised it was the aircraft he had flown in with me; he almost collapsed and had to be relieved from duty.
