While approaching Dinsdale at an altitude of 500 feet, the aircraft was 'attacked' by the pilots of two RAF Hurricanes that were conducting an unauthorized practice interception of the bomber. To evade the 'attack', the pilot of the Warwick attempted a steep climb when he lost control of the aircraft that dove into the ground and crashed in a field. All six crew members were killed.
