Vietnam War jets such as the B-52 Stratofortress could fly into the stratosphere or about 5 miles up, hence it's name.
The F104 Starfighter could fly at about 1,300 mph with a reported ceiling of around 64, 000 feet; the F100 Super Sabre about 800 mph and could only climb to about 51,000 feet.
Most commercial jets such as the B747 or A380 are able to fly about 300MPH against the jet stream, and 500MPH with it, at common altitudes of about 27,000 Feet high.
At their extremes they can fly 400MPH against the jet stream, and 550MPH with it, and fly at or above 30,000 Feet
about 42k ft
Ducks do not intentionally fly in jet streams, as they follow their natural migration patterns and do not rely on man-made air currents. Jet streams are high-altitude, fast-moving air currents in the atmosphere that can impact the flight paths of aircraft, but ducks do not navigate based on these air currents.
Over 70,000 MPH There is no such aircraft - you must be thinking of a video game or something.
most military air combat jet aircraft can go over mach 1.0, passenger aircraft fly at around mach 0.80
Up to 41,000 feet, like most other large jet aircraft.
varies on aircraft size
An aircraft that cannot fly.
The first turbojet aircraft to fly was the Heinkel He 178
The Harrier Jump Jet
Jets streams are found high in the atmosphere. They are fast-flowing 'passages' of air. They're useful to air-travel in that they can push aircraft faster than they would normally fly - saving fuel.
Commercial, jet engined aircraft, such as the 747, fly at approximately 40 000 feet. Propeller aircraft fly at lower altitudes
about as fast as a normal "SouthwestTM" jet can which is about 500 to 800 mph.
