In 1948 the Vickers Transonic Research Rocket became the first British aircraft to break the sound barrier in level flight. The un-manned aircraft was based on the design of the Miles M.52 reduced to 30% scale and powered by a rocket motor rather than a jet engine. Flights took place over the sea to the south west of England and were air launched from a de Havilland Mosquito with early trials being accompanied by a Gloster Meteor F.4 chase aircraft.
The Mosquito was modified as follows ...
Bulged bomb bay doors replaced
Mounting brackets added to the bomb bay doors
Connecting pipe and observation mirror added under the fuselage
The rocket itself and Meteor were built unmodified
The depiction presented above incorporates a large helping of 'artistic licence' for the following reasons ...
No photographic evidence that I could find was in colour
I could not determine the identity of the Meteor or any indication of it's colour scheme
The use of a chase Meteor was discontinued before the successful supersonic flight
I suspect the separation of the aircraft depicted is considerably smaller than it would have been in reality
