Answer: It has nothing to do with speed alone. Aerodynamics, weight, wind current, etc etc. all factors in flight. An ultralight with an imposibly good pilot, and the right windcurrent could stay in one place entirely (at least horizontally)
Answer: it goes about 500 miles an hour when it gets in the air but before it takes off it will get to 180 mph to get airborn but it can go faster the faster it goes the easier it is to take off and if you are planing on stealing a plane good luck!!!!!!!! dont do it or we will come for you
Answer: The top speed is between 630 and 700 miles per hour and the ceiling maximum (how high the plane can fly) is 45,100 feet. Each plane carries 53,611 gallons of fuel and weighs 833,000 pounds fully loaded for a long-range mission. With a full tank, the plane can fly half way around the world.
