In September 1925, the aircraft with the registration G- EBLP first flew.

Supermarine S.4 in the film

Very few photographs and films of S.4 exist, but remained five minutes of the film with the S.4 in the film Spitfire / First of the Few by and starring Leslie Howard ( which also occurs David Niven ) is obtained. In this film, drawings and photographs from the construction phase and the first launch and flight can be seen.

Crash cause

The instability during lateral flight was due to the minimal dihedral of the wings as well as a very small fin. Probably the lateral crash was during a role therefore inevitable.
