Miles Student
# Miles Student

The Miles M.100 Student was built as a lightweight trainer as a private venture by F.G. and George Miles with development started in 1953. Although not specifically a Miles product, it was promoted as a British Royal Air Force trainer but failed to enter production.

## Design and development

Building on the company's experience with the M.77 "Sparrowjet", the M.100 Student was a two-seat, side-by-side, all-metal jet trainer. The M.100 prototype was powered by a 400 kgf (882 lb) thrust Turbomeca Marbore turbojet and flew for the first time on 15 May 1957. Miles had hoped to secure an RAF order, but the contract went to the Jet Provost. The Student was proposed for several training programmes, but without success.

G-APLK, the sole aircraft, was allocated XS941 when developed in the Mark 2 version as a prospective Counter-insurgency type. It was tested by the Royal Air Force but was not accepted and therefore did not go into production.

The M.100 Student 2, re-registered G-MIOO, was badly damaged in a crash on 24 August 1985 and is now at the Museum of Berkshire Aviation .

The Centurion 3, 4 and 5 were planned variants with the RB.108, Gourdon and Arbizon engines respectively.
