Hi Barnes
Welcome to DogFight.
The mission of the game "capture the carrier" is to get possession of both carriers. You want to land on the carrier to do so. Once you land on the carrier put your brake on. You will notice 2 things happening. 1 the bar on the blue/white/red meter will start moving towards blue. That's a good thing. When the bar reaches the blue area the carrier is now in your possession. 2 the timer will be counting down. If it reaches zero you will crash and die. Take off, don't forget to press the brake again or else you will be kissing the carrier, I still forget sometimes. I recommend for you to start taking off with 20 seconds left for now as a noob and when you get better you can let that time run down to as low as 8 seconds.
The more blue the meter is the better. So if no reds are around you take off and land again and your timer will start all over again. Ideally bring the blue meter all the way to the end. If at any point you notice that the meters are moving towards either the blue or the red and you are no where near the carriers, that means that someone else has landed on it. Blue being your teammate, red being the enemy.
HERE IS SOMETHING THAT EVEN SOME EXPERIENCED PLAYERS DO NOT KNOW. When you do get possession of the carrier, that is when it turns blue, or if you land on a carrier that is already blue, (1) your plane will repair/reload itself. ALSO (2) the reds can not kill you with bullets IF YOUR BRAKE IS ON. So you can stay there and let them fire at you all they want. Just make sure that when it's time to take off again you do it when that enemy plane will not kill you immediately when taking off. You will get better doing this with experience. They can however drop a bomb on you and you will die. These 2 things only happen when the carrier is in your possession. If it is not than neither will happen. No repair/reload and you can be killed by bullets.
Get both meters into the blue section and you win.
GET IT NOW?
Have fun up in the skies.
