Mach 0.855 (650 mph) - The Boeing 747-8 (launch late 2009) and the Boeing 777.

yes

The Hummingbird best meets that criteria, it can even go into reverse, but it can't keep it up forever.

it flys at 45mph

No, they cannot. Planes can go up to 500 mph. Birds can go nowhere near this. The fastest known bird, The Peregrine Falcon can go up to a speed of 200 mph. Although this is fast for a bird it is no match for a plane.

At 37,000 ft, there's nowhere near enough oxygen to support the high oxygen demand of a high-metabolic organism (bird!), nor enough air density to support either flapping or gliding flight. So the answer is - no bird flies this high.

All of the majors do except Frontier and Southwest.

The smoking ban started in 1995 with California being the first state to enact it. Since then, many other states have followed suit, and most states in the United States do not allow smoking in any restaurants, bars or pubs anymore.

It depends on the medium that the propeller is in .

Aircraft propellors are very fast ; several hundred revolutions per minute.

Ship's propellors are much slower ; up to one hundred revolutions per minute.

makeing propellers takes years of prctace and buckets of skill. i recomend you buy one. thay are no more than $3 for a normal sized ones

Flying boats are airplanes that have the fuselage shaped like a boat. Pontoon planes are regular planes that have pontoons added to allow them to float.

Early aircraft propellers were made out of solid or laminated wood with later, more modern propellers being constructed from metal. The latest propeller designs are made out of composite materials.

While not called a Blimp the Brazilian inventor ( living in Paris) Alberto Santos-Dumont had a powered steerable balloon ( using adapted motorcycle engines) in the very early l900"s maybe l902. in l903, he permitted a Girl named Aida Acosta to operate the craft-a later model, called the No.9 on a flight around Paris- no problems. Miss Acosta was the first female Blimp pilot, so to speak-and this was almost six months prior to Kitty Hawk and the Wright Bros pattern of l903. ( which only lasted l2-l5 seconds). the Blijmp flight was a good twenty minutes or more.

Consider building a Squirrel. It just needs tissue paper and balsa.

Here's what a Squirrel looks like:

Balsa wood can be purchased locally at any hobby store or craft store.

Similar stores may carry propellers and the good elastic bands to use for wind up.

If you cannot get the propellers, there is a writeup on how to make one out of a Coke bottle at http://www.rubber-power.com:

Also for the propeller, you can try:

take the vortex part of the tip of a pen off.
get a paper clip (meta kind :P)
to make a prop. take two strips of balsa. put them at angle of choice, and slide the straight paper clip through it to form an x of some sort. now glue it together and you cover with tissue paper! and you have a homemade prop!!
i am Andrew Bradford, creator of the homemade prop specified above. it works out great if tampered with enough

nothing. you start the game with the blimp and can travel to all islands with it. you don't need a thing.

They are used to propel the airplane forward to get air moving across the wings. When air moves across the wings lift is created and you take off. Another interesting note: A propeller is an airfoil just like a wing is.

They make the airplane more versatile, less expensive, or both. A similar question is, "now that they have jet airplanes, why do they make propeller planes at all?" First, a propeller plane is less expensive than a jet. Let's give you six million dollars to buy an airplane, and make you buy new. $6 million gets you an entry-level jet. It will carry four executives if they restrict themselves to one suitcase each. The same $6 million will get you a Pilatus PC-12 or a Beech King Air B200, which are basically small airliners, or it will get you two EADS Socata TBM 850s, three Cessna Caravans, or three Piper Meridians. And that's just turboprops--$6 million will get you about a dozen piston planes. The other reason, and this is more important for a lot of operators, is that the propeller plane is more versatile than a jet. You can land on unimproved airstrips. You can land on top of mountains. In Mel Gibson's movie Air America there's a scene where he lands a Pilatus Porter on the side of a mountain--the real Air America pilots in Southeast Asia did that a lot. Jets, unless they're built for the military and equipped for rough airfield service, have to fly onto paved airstrips. Airbus is busy designing the A400 military transport. It has four turboprops. The drawback of a prop plane is that it can't be very fast--if you need a plane that flies faster than 400 knots, you need a jet. Prop planes don't fly as high as jets do; a King Air will fly up to 31,000 feet above sea level, while business jets routinely ply the skies above 41,000 feet. Propellers are not used to force air across the wing. they are used to create motion. In other word make the plane move and it's the resultant forward movement that moves air across the wing to create lift and get the plane off the ground

The time it would take would approximetly be around an hour or more but if it's a drawing or some easier crafts like making a painting, it would take a half an hour or 10-20 minutes. Hope this helps a lot!

Answer The old World War 1 biplanes were made of woodframe, supported by wires and covered with cloth. This process has continued to be used in airplane construction for many years and even some aircraft continue to have flight controls made of aluminum covered with fabric. The basic frame of the aiplane was made of wood. The frame was pinned or glued or attached with metal brackets. Then wires were attached internally to pull the wood joints together and add stiffness so the wings or fuselage would not flex as much. Over this, a fabic cover was applied using glue or "Dope". As the glue dried, the fabric shrunk and became very hard. This provided some stiffness and allowed the fabric to withstand the wind loads on the area not supported by the frame. After assembly of the fuselage and wings, more wire braces were attached to align and support the wings and tail.

They technically do both, as they fly when moving (nothing needs to touch the ground) and hover when standing still (unless they are turned off). This is assuming, of course, that altitudes less than a foot are considered flying.

To add: hovercraft can lift off, without their skirt, as they make fond use of the so-called "ground effect", much like helicopters do at a greater altitude. They keep lifted by sitting on the rotation of air beneath the vehicle and move forward by propelling the air behind the vehicle, rather than sitting on a big, inflated balloon (like many people tend to think). The skirt only serves as a mean for stability.

Technically, the hovercraft does fly, but is not considered to be an aircraft, whereas it does not elevate to great heights. Thus it is called a "hovercraft". People who operate hovercrafts, however, are generally referred to as pilots.

airplane, not airplan. you can't get an airplane in the game, though there is a few mods for pc, and there are helicopters.
