The rugged 'Twin Pin' was the second design from Prestwick based company Scottish Aviation to achieve production. A short take-off and landing (STOL) general purpose transport aircraft, the prototype flew on 25 June 1955 at Prestwick Airport, Scotland. The aircraft had a promising future until the second prototype crashed, putting off potential buyers.

Worldwide success

Only 89 examples were built, with the biggest customer being the RAF, though orders for limited numbers were received from various countries around the world that recognised the aircraft's capabilities.

Where did our Twin Pin serve?

The example in the National Museum of Flight served with the RAF as XM961 in Borneo and was eventually bought by civilian company Flight One at Staverton Airport, which had a small fleet of Twin Pioneers for aerial survey work. It was sold to the Museum after another aircraft was blown into it when parked during a gale in 1982.
