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.

G-APLK, the sole aircraft, was allocated XS941 when developed in the Mark 2 version as a prospective Counter-insurgency type.

The M.100 Student 2, re-registered G-MIOO, was badly damaged in a crash on 24 August 1985[1] and is now at the Museum of Berkshire Aviation .
