Carlisle
Quite nice to drop into Carlisle for fuel stops every now and then. City, when not flooded, is quite historic, but with all mod. cons. Well except the ability to get anywhere. Hills are great for walking, watch out for the military firing ranges though.
Gyros, helicopters, singles, twins are resident from memory. Bizjets and Tucanos visit regularly.
Runway plans lying around to flatten it out and extend for 737s.
As you don't get Virgin Atlantic, Blue, Nigeria or Express, you at least get Virgin Trains as compensation.
