The Prince of Wales and the Duchess of Cornwall survived an emergency helicopter landing last year, it has emerged.
Four other passengers were travelling on the Sikorsky S-76C helicopter on May 23 last year when the aircraft got into trouble, a report by the Air Accidents Investigation Branch (AAIB) said.
The heir to the throne and his wife were on their way to an engagement at the Hay-on-Wye festival in Wales, when the helicopter begin to veer - or yaw - to the right as it approached Denham aerodrome in Buckinghamshire.
The 53-year-old captain declared a Pan emergency, a less serious declaration than Mayday, and carried out a running landing at Denham.
It was described at the time by a royal source as "quite a hairy incident".
