How to execute flying kicks (twimyo chagi) in taekwondo 
Make a running start towards the target and jump off the leg you are not going to kick with. 
Fly through the air (several feet to several meters depending on your ability) and make contact with your target. The leg you jumped off from should be pulled up close to your body (including your hands) after you are in the air while flying.

Possible answers:
 1). Jump back up the leg you missed to bring your feet back up. Repeat the same exact process with the other leg.
 2). As you are in the air, swing your arms outwards and over your head in a clockwise motion to generate power. Spin your body around in front of your target.
 3). It is vitally important to keep your body protected from falling while landing. When the kick is completed, return to a good fighting stance.
 4). Swing your arms forward to protect yourself from flying kicks. Lift up all your bodyweight to steady your body as you are falling.
