Behind the Borders

How quickly could you act in defending your border!!!!!

Enemy planes have planed to infiltrate your border. Your mission is to identify and eliminate the enemy planes as indicated in every level to stay safe. Keep away from commercial planes because you will damage yours and fail the mission. Just swipe and destroy the enemy strategic flights. Be careful, though: the enemy military air forces escort themselves with commercial plane, eventually when you miss three enemy planes, your border is under serious threat!! GAME OVER!!!
