Saul was the pilot of Spitfire RR205 which departed airfield B.85 Schijndel in the Netherlands on a bombing practice. He flew to the target area but even though his plane was too close to the target he dived to the ground to drop his bomb. He released the bomb but because of the steep angle the bomb ended up between the aircraft propellers and exploded in mid-air killing Saul instantly.
