Not, strictly speaking, an Auster, but the unique Marshalls MA.4 prototype. The aircraft was converted from the prototype Auster T.7 (VF665); it was modified by Marshalls to specification ER.184D to enable Cambridge University to explore boundary-layer control by suction. For this purpose a revised wing, stronger undercarriage and enlarged fin and rudder were fitted together with a small gas turbine, which drew air through a myriad of 20,000 perforations in the wings, flaps and ailerons.. Lift was greatly improved and the M.A.4 flew as such from early 1959
Crashed and destroyed 8/3/1966: Control was lost at 3,500ft and the aircraft entered a dive from which it did not recover. It struck the ground inverted four miles from West Wratting, Suffolk, killing both the crew on board. No cause for the crash was released, but is thought that a trailing static tube, in the process of being hauled in, became entangled with the tail unit.
