Eulogy
Considering that the first (weren't there others?) Canberra Spec dates from 1945, the aircraft is quite amazing - and so elegantly simple ... The sleek fuselage, with the wings joining it on the centre-line and therefore needing no fairings to smooth out unwanted burbles in the airflow, which was also the case with the engines.
The engine position did need a main spar having to bridge the jet pipes, but this was a manufacturing inconvenience counterbalanced by the drag reduction. The low aspect-ratio wing gave it that high-altitude ability which helped make it outstanding and long-living, despite its low Mach capabilities, which were in any case far above those of contemporary aircraft, including fighters.
The trim runaway problem did cause much perturbation, until a T4 from Bassingbourn had a runaway "UP" and the instructor (?? Pete Stonham??)smartly wheeled it into a steep turn, then as speed dropped off selected full flap, thus restoring the aircraft to trim and a careful return to base, for the cause to be revealed and remedies found. Tks, Mr.Petter and his team !!!
