The aircraft landed safely

Sandy Ferrar of Scottish Airports Ltd, which manages both Edinburgh and Glasgow airports, said: "The British Airways Boeing 757 had suspected undercarriage problems and was diverted from Edinburgh to Glasgow Airport.

"It was flying up the central flight path and it was quicker for it to land at Glasgow than travel on to Edinburgh once the suspected problem had come to light.

"The flight landed safely at 1840 BST."

A spokesman for British Airways said: "BA can confirm that the BA 1454 service from London Heathrow to Edinburgh needed a precautionary diversion to Glasgow after a cockpit warning light indicated a possible technical problem.

"The aircraft landed safely but in line with emergency procedures passengers were evacuated via slides.

"None of the 119 passengers and eight crew was injured."

The spokesman confirmed that an investigation into the incident has been launched and added: "The passengers remained calm at all times and the crew performed in a thoroughly professional manner."
