23rd February 2010 at 11:55As mentioned in the Sunderland thread, this is the largest flying boat take off from a 'dolly' I'm aware of:
In 1962, it 'Flew from Abbotsford Airport runway No. 18 to the Fraser River at Sea Island - took off with the hull resting on a specially constructed detachable 4-wheel 'dolly' from which it lifted off when flying speed was reached. The dolly rolled to a stop at the end of the runway.'
(RAF Museum PDF Record Card.)
As it was not equipped with brakes, as can be seen above, it was retarded before the attempt by a rope attached to a (presumably full) Shell fuel bowser. This '40-minute test flight, flown by Slim Knights' was probably one of the most 'testing' take-offs in the type's career, notwithstanding the many open sea rescues by Stranraers in the war.
