Almost all airplanes hit the runway vertically less than a 100 feet per minute, which is like less than traveling 2 feet per second. However, the horizontal speed varies greatly. Glides can land at speeds below 40 mph, while large comerical airliners will land at around 150-170 mph. It depends on the design of the wing, the wing loading, and most importantly, when it will stall. Almost all aircraft basically stall (sometimes fully, sometines partically) upon landing.
Current commercial aircraft fly with a cruise speed depending on the model and make of the aircraft that ranges between Mach 0.81 through Mach 0.86, that is a speed in the range of 900 km per hour. We call this subsonic flight. Concorde flew with a cruise speed of about 2,100 km per hour. The future generations of very fast commercial aircraft will fly with speeds of 4-5 times the speed of sound, that is in the range of 4,000-5,000 km per hour. History of supersonic flight. Development of supersonic flight started already in the early fifties of the 20 th century, initially
