During my 2 years as a 'spotter' at EGNX, in the early 1970s, there was a C337 based there, G-ATNY.
About 10 years later a pile of AAIB reports appeared in our crew-room at EGCC, including one involving that a/c.
Fixed-wing as opposed to rotary-wing, yes, but I wonder how many similarities there are with this tragic event?
