Battle of Britain remake of PSS game CodeSVN

Added delay when squadron is taking off (one pulse to prepare after issuing order to take off).
Fixed issue with returning to previous position when squadron reached its destination (didn't work properly when target was located east of squadron).

Squadrons can land now and only on their side's airfield (British squadrons on British airfields, German sq on Germain airfields - which are non-existent now BTW). Also minor adjustment: right-click without squadron selected acts as left-click (may display info about clicked tile: airfield, radar, city)

Adjusted landing menu (box which appears when you select airfield as a target for squadron)

Clicking airfield when squadron is already selected invokes menu with choice of: landing squadron, circling over airfield, canceling.

Airfield is accessed with double-click now

Shows target of selected squadron as a red crosshair.
Bug fixed: When squadron was selected there could be selected airfield below too. Now only squadron is selected.

Squadrons are now able to take off :) You can choose single or multiple squadrons. Squadron which is taking off checks for collision with already flying squadrons. If there's flying squadron above airfield, landed squadron can't take off (unless former moves away). So if two or more squadrons are selected to take off, then they take off one after another, not the same time - first one takes off, moves away, then second takes off, moves away and so on.

Identifies which squadrons were selected to take off

Added ActionListeners to buttons in Airfield menu

Selected squadron is bordered in cyan.
Added crosshair indicating actual target of squadron.
