Chugalug 2
Those 2 Pilots flew their aircraft at high speed and low level directly towards fog enshrouded high ground into which they subsequently crashed. There was no distress call, emergency squawk or SARBE activation prior to the crash which occurred whilst the Handling Pilot was engaged in attempting an emergency escape manouvre. There was no evidence that the Passengers and Rear Crew had adopted crash positions or were even aware of any form of emergency, let alone the impending crash. No evidence was found of any technical malfunction that could have caused the aircraft to crash. Groundspeed at impact was in the region of 150 kts and the average groundspeed from the ATC fix departing Belfast to impact was 158 kts.
It should be remembered that, when the pilots initiated the waypoint change, it was too late at that point to initiate even an emergency climb to Safety Altitude maintaining safe separation from the ground.
