It's caused by r8755, but I'm not sure what the best way to solve this problem is.

I have found a work around. Perhaps it will help developers locate the problem too.

If you remove the airport you want to delete from the goto list for all airplanes you can delete the airport.
However, you do need to ensure that any airplanes that have just left the airport have made their turns away from the airport. That is they are not in the holding or takeoff patterns.

I've found out that simply making sure no airplane is currently going to the airport you want to remove or no airplanes are taking off you can safely remove the airport.

I believe that this became the case when patch r8921 was made. There are comments against that patch that indicated it fixed some airplane issues. I did a little more testing and found that the crash appears to occur whenever a plane is on-route to the airport you are deleting, or has taken off from, but not yet made the first turn.

I have created this patch to solve this problem. r8755 added an incorrect assert to airport_tile != 0 where GetAirport already handles this issue (as it did prior to r8755). A deletion of an airport causes airport_tile to reset to 0 and the next call of Airport() results in a debug error.

Attempt to solve this problem by adding a "dummy" State Machine. However, as the previous poster displayed, GetAirport already makes sure that the game asserts when a wrong State Machine is selected, so a simple removal of the assert would fix the problem as well.
