Air Ferry DC-4 crash 3 June 1967
I seem to remember that the faulty heater in this aircraft was a Janitrol. At that time I was a 1-11 line captain with BUA. The captain of the DC-4 had been a F/O with us but was offered a command elsewhere and so left. I had known him earlier in Silver City and Britavia and, knowing him to be very competant, was surprised that this tragic accident should have occurred to his aircraft until learning that he and his co-pilot had suffered from CO poisoning.
