There WAS a commercial plane that routinely flew over 1200 mph: The Aérospatiale and British Aircraft Corporation Concorde. That is to say, they CAN fly at 800+mph; it is technically possible and was historically accomplished many years ago (1969). Why they don't today tends to be an economic question and, to some degree, an environmental question, more than an engineering question.
Commercial software normally cost more and is made to look like it has more features when in fact it is normally around the same amount of features as the open source software. Commercial software is normally only needed it for bigger business needs.
There are many different types of planes aside from the commercial airliners that people use daily to get one from part of the world to another. More specialized airplanes include military helicopters, propeller aircrafts, helicopters, and pusher aircrafts.Commercial and navy are your basic groups of planes. Commuter planes carry a small number of passengers and commercial planes vary in passenger accommodation. Manufacturers like Boeing make commercial planes in all sizes like the Boeing 737 and Boeing 747.
790, more than 200 are leased.
Boats sinking and planes crashing both occur relatively rarely, but statistically, planes are safer than boats. The likelihood of a plane crashing is lower than that of a boat sinking, as commercial aircraft undergo rigorous safety regulations and maintenance checks.
Planes that are old and not built any more.
Jet planes normally fly in the stratosphere because the air is thinner at higher altitudes, which reduces drag on the aircraft and allows it to operate more efficiently. Additionally, flying at this altitude helps to avoid bad weather conditions and turbulence commonly found in the lower atmosphere.
None no the Boeing company invented many airplanes and they are about 9 different original commercial models with more that are actually a result of upgrading original airplanes.
most commercial airplanes use aviation fuel however some smaller planes may use a more concentrated version of aviation fuel
No, there are many more planes flying for longer periods than helicopters.
Planes can fly fifty feet off the ground if they need to. Commercial airliners fly in the stratosphere for two reasons: there's very little general aviation traffic up there (and most of the GA guys with planes who can fly that high are good pilots), and the plane is more efficient at that altitude.
Planes seldom crash more than once.
There are 56 such planes.
