The enemy fighter sat down on refueling in my territory without airfield

VTOL capabilities?

What is VTOL?

Vertical Take-Off Landing. Its used by modern day Harrier aircraft.

Did you capture the province during the time the units were en route? It's possible that they may still have carried out commands to land there on an airfield before you took it.

A-ha-ha! Yes - VTOL )))

No. It was already my area. Fighters departed there on patrol for interception of my attack planes, did some flying a little and suddenly sat down on refueling. On the picture it is visible that those who needed to be intercepted, fly to bomb interceptors

XD What the heck?!
