The Mosquito was certainly a wonderful aircraft, but don't forget that the single engine performance was not good, especially after take off. Single engine safety speed was in the order of 190 mph, with lift off at bout 130 mph. It took a long time to retract the undercarriage and clean the aircraft up. A lot of aircrew were lost in this way. It could bite very hard.
Read Neil William's account of dealing with an engine failure after tale off at Booker in "Airborne" and Don McVicar's book "North Atlantic Cat", the latter telling the story of ferrying (inter alia) Canadian built Mosquitos to Europe.
