Doesn't allow helos or harriers to do it either even though they should be able to because we don't currently support ground spawns, which would be needed to prevent those aircraft from using the runway. Even then, I don't know if they can be forced to *land* vertically. Fixes https://github.com/Khopa/dcs_liberation/issues/432
