An aircraft operated by British Airways CitiExpress has been forced to make an emergency landing for a second time in five days.
The captain of the air turbo-prop aircraft returned to Glasgow International Airport shortly after take off when he noticed an overheating warning light come on in the cockpit.
The plane was carrying two flight crew and two cabin crew as it left Glasgow at around 4pm, bound for Edinburgh Airport from where it was due to make a scheduled flight to Birmingham.
On Tuesday the same aircraft made an emergency landing at Prestwick Airport while taking 39 passengers from Glasgow to Belfast City Airport.
The aircraft underwent safety checks after that incident.
A spokesman for BA said: "The captain had a warning light in the cockpit not long after take off, and as a precautionary measure he decided to return to Glasgow.
"Safety and security is the absolute priority for BA and therefore the matter will be treated with urgency.
"We will be investigating whether there is a causal link between today's incident and the one earlier this week."
