A Flybe flight travelling from Aberdeen was forced to turn back after declaring an emergency on board.
The alarm was raised after a passenger on-board Flight BE1030 took seriously ill as the plane reached around 22,000ft.
The aircraft was travelling to Manchester Airport and the flight has now touched down in Manchester after a 90-minute delay.
A spokeswoman for the airline said: “Flybe confirms that the above flight returned from airborne to Aberdeen airport this morning after a passenger on board became unwell.
“The aircraft has subsequently continued its journey to Manchester with an estimated 90 minute delay.
“Flybe apologises to its passengers for any inconvenience experienced as result of the delay to their travel plans.”
