Camilla Parker-Bowles narrowly avoided two mid-air collisions in the space of an hour during a helicopter ride from the Queen's Sandringham estate to her home at Ray Mill in Wiltshire.
The Duchess of Cornwall, who has a fear of flying, terrifyingly came within nine seconds of a head-on crash with an aircraft carrying sky divers in July 2018, the Mail on Sunday reports.
WATCH Camilla scold Kate Middleton for speaking out of turn:
Air traffic control at the Royal Air Force Marham in Norfolk who were monitoring the Duchess' flight told Express.co.uk the potential for a collision had been "high", after the pilot of the other aircraft failed to alert air traffic controllers to their altitude.
RAF Lakenheath made numerous attempts to contact the pilot, who was flying a De Havilland Canada DHC-6 aircraft, but he failed to respond as he was "distracted by passengers in the back", according to Express.co.uk.
It was the pilot's eighth flight that day, reports say.
The 71-year-old Duchess' Sikorsky S76 helicopter was forced to raise altitude to 5,400ft, but when the aircraft descended to land the pilot initiated another emergency manoeuvre at 161mph to avoid a glider which had been "flying into the sun".
The frightening incidents occurred on July 25 last year, after Camilla and her husband Prince Charles attended the Sandringham Flower show, a report from the UK Airprox Board reveals.
The Prince of Wales remained in Norfolk at Anmer Hall, the country home of his son Prince William and wife Kate Middleton, Duchess of Cambridge.
