Emergency slide was accidentally deployed on Virgin Atlantic 747 at Manchester Airport.
As Virgin Atlantic Boeing 747-400 (G-VAST) was about to be catered for flight #VS75 to Orlando, an emergency slide was activated, possibly after the door wasn’t properly disarmed.
The flight #VS75 finally departed to Orlando with a delay of more than 6 hours.
