Canadian Comet 1's
Don't forget that CPA (Canadian Pacific Airlines) also operated Comet 1's briefly. I'm not certain they ever achieved scheduled service but, if memory serves correctly, the Karachi takeoff accident was a CPA Comet 1 on a round-the-world proving flight which rotated early and failed to become airborne, due to excessive drag and/or loss of engine thrust.
I believe later Comets had a protruding upper lip on the four intakes to better feed the engines at high AOA. Another outcome of the investigation was the eventual creation of the FAR 25 reg that today requires Vmu (minimum unstick speed) to be demonstrated on all transport aircraft during type certification.
