There are two groups of aircraft that fly in different modes 1. IFR - ´ instrument flying´- these are recognized and controlled by Air Traffic Control (civil and military, which cooperate with each other) 2. VFR - flying ´for visibility´ - these aircraft fly - usually, without ground control (they fly in other routes), but they are small planes (UL ...) - whose pilots know (according to maps) where they are not allowed to mix But what has which plane loaded and whether the "bomb "just unlocks, no one knows from the ground. :O
