-> now the sound of the alarm siren last longer and it is louder. The alarm is also heard only at the airport and in its vicinity - not on the whole map as it was before;
-> added missing "sounds of door opening" to all usable doors in the airfield buildings;
-> now both hangars are accessible. I needed to edit the hangar next to the Ju87 bomber, because by default the player cannot enter it;

-> i optimized the patrol route of the German soldier, who started the patrol next to one of the hangars. I extended his patrol route along all fighters parked below the camouflage nets;
-> added "wind flags" for measuring the wind direction and intensity (see attached picture);
-> added "reflective markers" to ends of both runways (see attached picture).
