The Old Timer

Jimbo is in thick fog when he comes across the Old Timer (from episode 1.02) in his flight corridor, trying to find his way back to the Midlands. Jimbo is denied permission to land at London due to the fog, and is redirected to Birmingham- where the Old Timer is headed. Denied permission to land there because they've got a car race on, the two are sent on to Manchester, which turns out to be closed due to a storm. Then Glasgow send the pair away because they're snowed in, and they finally return to London, where the fog has cleared.
