It has only two landing wheels--one in the front and one in the back (called bicycle landing gear). The chase car tells the pilot what to do to keep the plane balanced on two wheels as it goes down the runway. At the end, as it slows down, it reallly wants to tip over. Before it can, ground crews run up and put wingtip stanchions with wheels on them under the wingtips to complete the landing gear so it can taxi. Really amazing
