A further drone sighting has again disrupted the UK's second biggest airport, with flights grounded and passengers unable to fly.
Aircraft were left circling above the area during the latest alert, which came at about 17:10 GMT. Flights resumed less than 90 minutes later.
A spokeswoman for the airport said the suspension was only as a precaution.
He said military measures had been put in place that meant it was safe to reopen.
