The key to the dragon’s superior mobility and maneuverability, the glide maneuver gives the dragon formidable speed in avoiding danger or swooping in for the kill. One of the dragon’s combat advantages lies in its mobility. No other weapon, biological or mechanical, can come close to the dragon in top speed, total flight distance, turning radius or acceleration.
The glide maneuver, in particular, uses sudden acceleration, deceleration and turns to evade most projectile attacks. For even the deadliest of attacks is powerless if it cannot find its target.
