VTVL

VTVL stands for "Vertical Takeoff Vertical Landing". This is when a vehicle takes off from the ground and flies up in the air, then lands back down to the ground in the same spot after it is done flying. VTVL is used in many kinds of vehicles, like rockets and drones. Rockets use VTVL to help them go into space and explore, and drones use it to lift off and take pictures or videos.
