A British Airways captain was forced to make a Mayday call just minutes before landing after fumes reportedly filled the cockpit.
The flight from Athens was on the approach to Heathrow when the co-pilot steering the plane fell ill, forcing the captain to take over and put on an oxygen mask.
The terrifying scenes unfolded in darkness just four nautical miles before the A320 aircraft touched down at Britain’s biggest airport.
The latest incident, on Flight BA633 on January 2, saw the first officer on the Heathrow-bound jet fall ill with two minutes to go before landing.
Medical crews met the plane immediately after it was safely down and assessed the first officer, with passengers oblivious to the drama. Insiders said he fainted and was slumped over the controls but BA denied this, MailOnline reports.
