A near-miss involving a military jet and a passenger aeroplane in the west of Scotland has sparked an investigation.

The incident took place 25 miles west of Glasgow.

An inquiry has also been launched into a near-miss between two British Airways passenger planes on domestic flights - one of which had taken off from Glasgow.

Two BA planes were involved in one incident

The first incident involved a Shorts 360 aircraft from Islay, which was operated by Loganair.

It was being guided into Glasgow by air traffic controllers when it came close to colliding with a Royal Air Force jet at an altitude of about 5,000ft some 25 miles from the city.

The Civil Aviation Authority (CAA) is carrying out an inquiry into the incident, which took place last month.

An air proximity report has been filed with the CAA and investigators will examine radar records to discover what happened.

The incident came to light two days after the most recent near-miss over mid Wales - which itself took place only days after 71 people were killed when two jets collided over Germany.

A Bristol to Newcastle flight came within 1,000ft of a plane travelling from Glasgow to Bristol at about 1900 BST on Wednesday.

The two planes must have been closer together than 1,000ft or no report would have been filed

CAA spokesman

Emergency anti-collision systems were activated and both planes were steered apart.

BA said it was "unlikely" the passengers were aware of the incident.

A CAA spokesman said: "An investigation is under way but the two planes must have been closer together than 1,000ft or no report would have been filed.

"Nobody knows how close they were at this stage but closer examination of the facts and courses will reveal more."

The Embraer 145 jet from Glasgow had been carrying 43 passengers, while the Dash 8 aircraft leaving Bristol had 22 passengers on board.
