Short S.30 Empire Flying Boat G-AFCK, named ‘Golden Horn’ departed from Lisbon on December 30, 1942. The flying boat returned to Lisbon due to a failure in the no. 4 engine. A replacement engine had to be ordered. On the subsequent test flight on January 9, 1943, a fire broke out in the no. 3 engine due to a failure of the no.4 cylinder. The propellers could not be feathered and once the oil-fuelled fire took hold it could not be controlled. The cockpit was filling with thick smoke. The co-pilot had opened his window which drew more smoke from further aft in the cabin onto the flight deck. The captain attempted an emergency landing on the Tagus River. On landing the aircraft porpoised and crashed, disintegrating. There were six authorised crew and a further nine unauthorised passengers. Only two survived the crash.
