Scotland's longest running airline has marked a half century of operations.

For 50 years Loganair has flown daily routes between Glasgow and the Scottish Highlands and Islands, providing a vital link to and from the mainland.

The airline marked the occasion at Glasgow Airport with a water cannon salute to celebrate 50 years in the aviation business.

Founded in 1962, the airline's first flights were air taxis for a construction company working between Edinburgh and Dundee.

Then due to local demand an inter-island service for Orkney and Shetland was introduced.

More routes to and from the Highlands and Islands followed shortly after.

The company now carries not only passengers, but mail, cargo, and other essential products and services to the islands, as well as operating charter flights for the North Sea oil industry.

Chairman Scott Grier, who has been with the company for 36 years, said that the company operated "lifeline services" that would hopefully continue for at least another 50 years.
