London to LA plane turns around as passengers & crew fall ill, then air is tested before paramedics are let on & luggage seized for checks

There was a strange occurrence on American Airlines Flight AA109 from London to Los Angeles. 6 cabin crew members and two passengers suddenly fell ill, forcing the plane to declare an emergency landing and return to London. When they landed at Heathrow, passengers said they were not told anything other than they should remain in their seats. An official from the London Fire service got onboard the plane to carry out tests on the air inside the cabin before passengers were allowed to disembark but their luggage was confiscated for analysis.

Panicked passengers told of the moment a plea went out for any doctors on-board the American Airlines flight, before the captain declared a 'medical emergency' and returned to London.

American Airlines has so far refused to speculate on what may have caused people to feel unwell, saying only that 'paramedics evaluated passengers and crew. None requested further medical attention.'
