Military fighter jets typically fly at altitudes ranging from 20,000 to 50,000 feet, depending on their mission and capabilities. Some advanced fighters can reach even higher altitudes, up to 65,000 feet or more, particularly during high-altitude reconnaissance missions. The specific altitude can vary based on factors such as the aircraft type, operational requirements, and airspace regulations.
They fly in air. High-performance military fighter jets have engines powerful enough that they can fly straight up, like a 'rocket ship'. But aside from those, all airplanes need air in order to remain aloft.
The fly and then they shoot (:
They do make noise. If they fly very high, then you can't hear them.
Most military fighter jets run with a single pilot and a flight officer. The Flight Officer is not trained to fly the aircraft.
Some models of fighter jets have flown suborbital trajectories with apogees above 50 miles (80.47 km).
If you mean fly on thermals like some gliders, NO.
they fly almost above 15km, where atmospheric pressure is very low.
The fly on the same principle as any aircraft the difference being they are propelled by jet rather than propeller.
Military aircrafts fly the same height as the commercial airplanes do. The cruising altitude maybe 30000 feet to 45000 feet. Planes like SR-71 have gone upto the maximum of 85,000 feet.
No. The fastest wind gust ever recorded in a tornado was 302 mph. By comparison, commercial jets regularly fly at 500 mph. Some fighter jets can fly at over 1,000 mph.
Radios or talkies. It's basically the only way to communicate.
Probably not in commercial service--the FAA has mandatory retirement ages, and a Vietnam-era fighter pilot is past those. But if it's his own plane, and he's current and trained to fly jets, he could fly it.
