Off topic, but of local interest, I found a website with copies of old airline timetables.
In the late 1950's Silver City operated a summer service, three return trips on a Saturday, between Carlisle and IOM. As Carlisle Council did not purchase the airport until 1960, these flights were operated from Silloth. I believe they used the B170 Bristol Freighter.
