It was a lousy airliner. George Lothian, one of the first TCA pilots, mentions it in his book "Flight Deck" -- which is a very good one, BTW. He was a Ferry Command pilot, with many Atlantic crossings, and he didn't like the aeroplane. Too many engine shutdowns, and without the 2-stage blower it was not able to get above the icing in the winter ocean weather fronts. Each trip was a bit of a victory, especially coming back to Canada against the wind.
