In 1953 the Miles brothers decided to design and build a prototype jet trainer which would be much less costly than the Jet Provost, then under consideartion for the RAF. The M.100 Student was built as a private venture and, owing to the limited resources of the company, construction took a considerable time. As with many Miles designs the Student included a number of unusual features for its time, but it was May 1957 before it flew and too late to be a contender for the RAF contract. The frame has carried the previous registration G-APLK and RAF test serial XS941.
