High Quality Content by WIKIPEDIA articles! 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 Harrier jump jets can takeoff and land vertically. Rockets also usually takeoff vertically, but some designs can land horizontally.
