Ambrosini S.7 Freccia
When SAI Ambrosini embarked on the creation of a light jet with supersonic capabilities, it was decided to proceed step by step, with experimentation.
A standard Ambrosini S.7, named Freccia, was equipped with a 45° swept wing.
First flown on 18 July 1952 on the military base at Aviano, the pilot was Ireneo Di Crescenzo. Test were flown until 1 August 1952. After tests with the sweptback wing, designer Sergio Stefanutti designed the Sagittario (Archer) powered by a 400kg thrust Turbomeca Marbore turbojet.
