Ancient Aviator,
Apologies for a tardy reply but we had unexpected "Guests" when a Niece and her Family came to stay having been forced to abandon the flooded Camp Site in Brittany at which they had been staying.
The piece of equipment I was refering to was that which WK is so insistant was the cause of the crash. Persons who were present at Aldergrove, and who had walked out to the Aircraft with the Crew, have given testimony on this thread that such equipment was NOTfitted to the aircraft that day. No such equipment was recovered from the Crash Site.
Now we have WK suggesting that the investigation as to whether or not the crash was the result of sabotage is itself suspect. Given the situation in NI at the time, and the importance of the Personnel who were the aircrafts passengers, such investigation took the highest priority. There was no evidence of sabotage or any pre-impact explosion. Of course it is possible that the disparate altimeter subscale settings may have caused some confusion during the final desperate escape manouvre.
Incidentally, may I ask if you looked up the meaning of the word "Ancient" in a military sense before deciding on your user name. Try Shakespeare's Henry IV Part 1 Ch 4 V 2 & V 21.
