@igorlikespike: I'm glad your problems have been solved
@BigWalleye: Thanks for helping!
@all:
I have uploaded a new version which also contains an airbase which will be activated when you are detected. The airbase is placed at several ports/regions. Now you can expect heavy air cover in regions close to British main ports, e.g., Gibraltar, Malta, British Isles, Alexandria, Halifax... if you are detected.
The air base currently uses only Hurricanes, however, you can change the plane type as you wish (but don't change the number of squadrons).
