Two pilots have been arrested for allegedly attempting to fly a transatlantic passenger plane from Glasgow Airport while under the influence of alcohol.

The captain and first officer are due to appear at Paisley Sheriff Court on Tuesday following the incident on the Air Transat aircraft on Monday afternoon.

It is understood that cabin crew raised the alarm shortly before the Toronto-bound plane's scheduled take-off.

A Police Scotland spokesman said: "Police can confirm two men aged 39 and 37 have been arrested in relation to allegedly being impaired through alcohol under the Railway and Transport Act 2003. They will appear at Paisley Sheriff Court on Tuesday."

Passengers were given overnight hotel accommodation and the rescheduled flight is expected to depart on Tuesday.

A spokesman for the Canadian airline said: "Air Transat has learned of the arrest on July 18 of two crew members assigned to its Glasgow-Toronto flight.

"We will await the results of the investigation and judicial proceedings before commenting on the matter before making any further comments. The safety of our crews and passengers is, and will remain, a top priority at Air Transat."

Some passengers voiced their anger over an apparent lack of an official explanation over the delay.

A rescheduled flight departed from Glasgow for Toronto on Tuesday.
