Join the tunnel of the death! Do not be afraid it mis not that bad. In fact, it is a tunnel of entertainment and overcoming your possibilities. Control the airplane and fly as far as possible. If you get into the desperete situation you can use rockets and shoot your way out. Otherwise, primarily avoid all obstacles and collect coins. For the coins you will buy new airplanes. If you lose all your ammunition, you can collect it along the way. It's just more rare. So do not hesitate, get on the board and become a legendary pilot. Have fun.
