Not something you see in your local supermarket's carpark every day. The aircraft had an engine failure the day before and landed about a mile away. It was then going to be towed overnight to Prestwick Airport (home base) but there wasn't enough time before the traffic got busy. So it is parked up waiting for the wee small hours before resuming its tow back to base, about 4 miles as the crow flies but double that going by road.
