Plane makes emergency landing
An inquiry has been launched after a plane with 12 people on board was forced to make an emergency landing at Aberdeen Airport.
The Eastern Airways Jetstream 32 had just taken off for Newcastle when the pilot reported a hydraulic problem.
An airline spokeswoman said the front undercarriage had failed to retract completely.
A full emergency was declared while the three crew and nine passengers circled Aberdeen for an hour before landing at 1345 BST.
The airline was arranging for another aircraft to fly the passengers to Newcastle.
