I build F-35s as a career. The B model does not normally do vertical takeoffs since this compromises the surface underneath, risking damage and blowing FOD into the plane & engine inlets. As can be seen in the video, a short takeoff run is nearly always performed for the F-35B. It can land vertically, however, which requires less thrust. This is an edit of an earlier comment where I said the B model cannot takeoff vertically. After seeing comments here, watching VTOL video,

Instead of everybody walking behind that unmanned vehicle a couple of them could sit in the seats and ride and one of them could even drive it since it has controls just like a manned vehicle.

Excelente diseño del f35,aunque se vería más imponente que la compuerta de la turbina del medio que sirve para el despegue vertical,se habrá hacia un lado y no hacia arriba,así no queda de contraviento mientras esta abierta y el avión es impulsado hacia delante..

These are short take offs not vertical takeoffs. I wonder if all the major flaws and bugs will ever be ironed out in this expensive weapons system
