Emel.OW on the 28-th of February 13 IL-76 with russian troops landed at military aerodrome close to Simferopol. They were flying without any FPL and at extremely low altitude, not to be seen by radars (but two of them squawked for few minutes with A/C during approach) Later russians got control of each aerodrome around Crimea and blocked ukrainian military units. First time when russians, armed with PKMS, entered UKFF tower, they prohibited Turkish flight to land.
So it is an INVASION. And don't be offended because of it. Ur president Putler started cold war.
