VTVL

Vertical takeoff, vertical landing (VTVL) is a form of takeoff and landing for rockets. Multiple VTVL craft have flown. As of 2012, at least six VTVL rocket vehicles are currently under development at four different aerospace companies. VTVL is often proposed as a viable technology for reusable rockets.

VTVL rockets are not to be confused with aircraft, where that class of aircraft which takeoff and land vertically (helicopters, etc.) are known as VTOL aircraft.
