Disable an airfield?

[salmo]

ATAG_Collander has asked about a method to disable an airfield. Does this work? I can't get the call to the routine right so haven't been able to check it.

I think this feature is part of the unfinished resource managment i found in code. At time it seems it's not available, no positive tests for me, may be others have.
But if you use a spawnaerea you can destroy it and reload it at later time with ISectionfile.
