The simple answer is that they use an airfoil. How the airfoil works is the complicated answer. You know about air pressure, right? It's constantly pushing on everything from every direction. An airfoil changes that. The top, or cambered, side has a hump on top of it, for lack of a better term. The bottom side is just flat. If you were to measure the distance from the leading edge (front) to the trailing edge (back) on the top and bottom, you'd notice that the distance on top is longer than on the bottom. This is key. When an airplane moves, air rushes over the wing on both sides. However, the air going over the top must go faster to keep up with the air on the bottom because the distance over the top is longer. If the top was flat like the bottom, then the air pressure would be the same on both sides. But because the air on top has to move faster than on the bottom, it can't stay and push down on the wing as long. This results in lower air pressure on top than on the bottom. The faster the plane goes, then the stronger this effect is. At 50 m.p.h., the effect is not strong enough to lift the plane unless it's a very, VERY light plane. At 180 m.p.h. (standard takeoff speed), the effect is so great that is able to counter the effects of gravity and the plane will leave the ground. So the entire source of lift is from air on the bottom pushing up harder than the air on the top. To see this effect at home, take a strip of paper, hold one end close to your mouth, and blow across the top. The same principle is at work, only on a much smaller scale. I hope that this explanation was easy to understand. If not, then I'm very sorry, but I can't think of a simpler yet accurate way to say this.
The words weight, fly and sand have "fly" in common, because together they can form other words. Their direct relationship is: fly, fly weight, and sand fly.
A house fly can fly at an average speed of about 4.5 mph.
A fly can fly in a car because it is able to navigate and maneuver quickly in small spaces, using its wings to propel itself in different directions. The fly's ability to react quickly to changes in its environment allows it to fly around inside a moving car without colliding with objects.
No, a fly would not be able to fly in a vacuum because it relies on air resistance and pressure to generate lift and maneuver in the air. In a vacuum, there would be no air molecules for the fly to interact with, so it would not be able to fly.
When you get the fly swat out, the fly may sense the sudden movement or change in the environment and decided to fly away to avoid the potential threat. Flies have quick reflexes and are sensitive to changes in their surroundings, allowing them to escape harm.

Because she found it exciting.
Some people want to travel during the day, some want to travel at night, some planes travel faster than other planes, some planes fly a short distance, some fly a long distance. Sometimes the weather effects the way planes fly.

According to the US Immigration Bureau, the majority of legal immigrants are Asians. The percentage of Asians has been increasing for the past ten years into the US.
The impact on airplanes might include the environmental impact of using airplanes on the planet. The impact might also refer to the amount of force exerted by the airplane when it crashes or comes in contact with the ground.
Any hobbie store you can find foam RC airplans and other airplanes yu might want. Ask the stor clerk if he knows where to get them and you should be on your way.
