A drawn airplane flies along a lined notebook sheet and difficult tests await it. Soon he will cross the conditional border and the enemy territory will begin, which means shelling will begin. Your plane has no weapons and will not be able to shoot back, so we came up with an alternative defense, which is quite logical in this situation. Everything is simple - draw a barrier before the air transport and it will look like a regular line, but it is so strong that it can absorb flying projectiles. But its action is short, when it is completed, draw a new defense line in Shoot Heck.
