What is considered on the runway

[Cheif Operations Director]

On the island airfield in the hangers on considered on the run way. I have a full fighter squadron stationed their but now I cants spawn anything on the island. The only way I can fix this is too move them onto the grass but the terrain is aweful so it would be nice if that did not count as on the runway,

It will count as the runway because the planes will spawn since the planes spawn there.

But the one with the Easter egg should not count.

Unless you have that as an alternate launch site (making history expansion), and you want to use it...
