Alright, most of these people are idiots and answering the question how fast do airplanes cruise.
The take-off or "rotate" speed for airplanes differ depending on size, type, etc...
On average lets say most of your small single engine airplanes rotat at about 55 knots which equals about 60-65 mph. They then speed up during climb to about 80-90 knots (about 90-110mph). Cruise speed is anywhere from 100-140 knots (115-150 mph).
Now obviously as the airplane gets bigger it tends to get faster.
Your jet aircraft usually stay around the same speeds though. Rotate speed is about 130-150 knots (150-170 mph). They then cruise anywhere from 250-400 knots (290-460 mph). Such a big possibility for the speeds because it all depends on the airplane.

Small airplanes lift off at speeds as slow as 35 MPH. Typical single-engine light planes lift off at around 55-60 MPH. A 737 needs 150 MPH, and a heavily loaded 747 may need to get as high as 225 MPH, though usually more like 160-180 MPH. Most jet airliner takeoffs are in the range of 150-180 MPH. It depends on weight, height above sea level, temperature, and winds.

Kiersten, the B-737 you were in was probably going between 140 and 160 mph at lift-off. The exact speed varies depending on the aircraft's weight, the temperature, the air pressure, and the wind. Generally speaking, the higher the weight, the lower the pressure, the higher the temperature, and the less the wind speed, the higher the speed necessary for the aircraft to take off. The higher the altitude of the airport the higher the speed is required, but all the airports in Florida are between sea level and 22 feet above sea level, so that doesn't make much difference between them. At a place like Denver or Reno things are different. It is physics at work. Take-off speeds vary for each aircraft. Regards, Dan

As fast as necessary to produce enough lift so the aircraft can safely fly. Some can take off with a forward speed of 40 miles per hour, others need speeds that are more than 150 miles per hour, & a few even more than that.

That depends upon the aircraft. Could be anywhere from about 40 MPH to well over 150. Most commercial jets rotate between 140 & 180 MPH airspeed.

usually mesured in knots (1knot =1.15mph) so 100 knots is 115 mph.
Cessna's are around 60 knots (if i remember correctly)
Commercial aircraft around 140 knots
Fighters around 150-160 knots
Also flown gliders that take off (when towed of course) at around 30-40 knots
all depends on fuel weight though

It depends on the type of aircraft, the cargo weight the amount of fuel on board, the lenght of the runway, and the altitude it has to reach.
