A 10ft drone came so close to colliding with a passenger jet that it covered the plane's windscreen.
The Airbus A320 had just taken off from London's Heathrow Airport back in May and was at 9,000ft when the near-miss occurred, The Sun reports.
A report into the incident by investigation bod UK Airpox Board said: 'Both the Captain and First Officer saw a bright white object pass overhead from the opposite direction.
'It appeared to be approximately two-three metres in size at the very least.'
The report added: 'It may have been larger as it filled a good proportion of the windshield.'
