Narrative: During the Battle of Britain of Britain air show at the Imperial War Museum, Duxford, Cambridgeshire two P-51 Mustang aircraft contacted each other during the display. Both aircraft landed safely, but G-BIXL, "Miss Helen" sustained damage to the left hand horizontal stabilizer.
A video from the mishap seems to show that the stabilizer was hit by the prop of the other Mustang.
UPDATE: The preliminary AAIB report was published on 12/7/2018, and the following is the summary fro that report...
"Two P-51 Mustangs were taking part in a display sequence at the Battle of Britain Air Show at Duxford, Cambridgeshire. The accident occurred as they were joining formation with a Boeing B 17G in preparation for the next part of the display. The pilots had briefed and agreed that the lead P-51 would join on the B-17’s right side and the other on its left side. However, during the display both pilots tried to join on the B-17’s right, resulting in the two P-51s colliding. They landed without further incident.
A number of human factors were contributory to the accident. Most significantly, although the P-51 pilots had performed a ‘walk through’ of their display, they did not include the part involving the B-17. The CAA has added some additional guidance to Edition 15 of CAP 403, Flying Displays and Special Events: Safety and Administrative Requirements and Guidance, with regards to performing walk throughs of displays prior to flight.
