Vertical takeoff, vertical landing (VTVL) is a form of takeoff and landing
Takeoff and landing
Vehicles that can fly can have different ways to takeoff and land. Conventional aircraft accelerate along the ground until sufficient lift is generated for takeoff, and reverse the process to land. Some aircraft can takeoff at low speed, this a short takeoff. Some aircraft such as helicopters and...

A vertical take-off and landing aircraft is one that can hover, take off and land vertically. This classification includes fixed-wing aircraft as well as helicopters and other aircraft with powered rotors, such as cyclogyros/cyclocopters and tiltrotors...

). Multiple VTVL craft have flown. , at least five VTVL rocket vehicles are currently under development at four different aerospace companies. VTVL is often proposed for reusable rockets.
