I was quoting the BOI which consisted of a Wg Cdr and a Sqn Ldr who were both experienced Chinook Pilots, and an Engineer Officer experienced on the Chinook. Apart from the Board members the Stn Cdr Odiham (himself a Chinook pilot I believe) also commented prior to the BOI reaching HQ 1Gp. It was the Stn Cdr Odiham who first found negligence in respect of the conduct of the flight. The Stn Cdr Aldergrove commented on only those matters which fell under his juristiction.
The Aircrew members of the BOI were quite specific - the forecast weather would have permitted a climb to Safety Altitude in the vicinity of the Mull. It would not have permitted a medium level transit across the Highlands en route to Fort George.
When, however, the pilots changed the waypoint from A to B they were already too late to conduct a cruise climb to Safety Altitude. They were also too late even to conduct an emergency climb to Safety Altitude.
Trust you are keeping well.
