A British Airways plane made an emergency landing at Heathrow after both pilots became "unwell" at the controls.
The captain and first officer of an Airbus A321 reported feeling light-headed while the jet was on its way to Glasgow after taking off from Heathrow last month.
One passenger on the Airbus A321 heard a "panicked" captain call for a senior member of the cabin crew to come to their aid.
The pair were given oxygen masks before requesting an emergency return to Heathrow and landing the plane safely. The incident is being investigated by the Air Accident Investigation Branch.
It was also reported by a passenger on the flight on a professional pilots' website. "I was on the London to Glasgow flight yesterday, departed Heathrow at 4pm-ish, got airborne, at approx 20 mins into flight a very abrupt and panicked message came over the PA from the pilot," he said. "It later transpires that both pilots became lightheaded/ dizzy/ unwell at the same time, in my book that's serious."Reuse content
