British Airways pilots of a Boeing 777 got sick at the controls because their cockpit was starved of air while flying across the Atlantic, an official report said Thursday.
The jet carrying 235 passengers and crew to Seattle on March 6 returned to London's Heathrow Airport for an emergency landing after all three crew members on the flight reported feeling unwell.
The pilots wore oxygen masks and opened the door between the cockpit and passenger cabin— in contravention of security rules brought in after 9/11—according to the report by Britain's Air Accident Investigation Branch (AAIB).

The report concluded that the air supply was blocked by debris including wire, bubble wrap, and insulation material trapped in a ventilation duct.
