Was it not a Chinook that recovered Stornoway Coatguard SR61 to ABZ from Stac Pollaigh, circa 2001 after having, ahem, malfunctioned in the hover, close to the mountain, striking said mountain? As a Bristows engineer said to me at the time, problem was, the recovered cab kept trying to fly whilst being flown. Rgsd to one and all from a gale lashed ABZ. Preparing to be flamed. Are you out there, DSS? ALU
