British Airways flights have been "grounded" following a major IT meltdown, resulting in chaos for "thousands of passengers".
The glitch has meant that planes are unable to take off and phone lines are down, whilst pilots have been unable to upload documents containing vital information required to fly safely.
Planes cannot be flown by pilots electronically and must now be operated manually, The Times has reported.
Queues are reportedly building at Heathrow Terminal 5 due to the problem, the outlet reports.
