Why do planes look the way they do?
The shape of an airplane’s wings is what makes it possible for the airplane to fly. Airplanes’ wings are curved on top and flatter on the bottom. As a result, less air pressure is on top of the wing. This lower pressure makes the wing, and the airplane it’s attached to, move up.
Why do planes sometimes look like they are hovering?
One reason is the aforementioned higher air density near the ground. The other is due to wing flaps, which are activated during takeoff and landing. When the flap is raised, it increases the coefficient of lift associated with the airplane significantly.
Can an airplane stand still in the sky?
Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare. To stay in the air and sustain its flight, an aircraft needs to be moving forward.
Why do planes look like they fly slow in the sky?
A line of fence posts far from the road do not snap by so quickly. The farther from the road the posts are the slower they appear to go by even though they go by at the same rate. With the plane, the plane is in motion and you are stationary. Why do planes look like they fly slow in the sky?
Why do planes not fly over the Pacific Ocean?
You might think it was a safety issue. The Pacific is the largest and deepest of the world’s oceans. If a plane encounters a problem over a seemingly endless and bottomless pond of water, the pilots are going to have a rough time finding a safe spot to set her down. Guessing that it is a safety precaution wouldn’t be entirely wrong.
What makes an aircraft stealth in the air?
“Boundary layer” aerodynamics, referring to the air flow surrounding a weapon or platform as it transits, can greatly impact the flight stability and stealth characteristics of an aircraft.
What does it look like when a propeller does not turn?
If the timing is precise, it looks like the propeller did not turn at all. But if the blade interval doesn’t exactly match the camera interval (or a multiple of it), then the propeller will seem to turn slowly forward or backward.

Can you tell the altitude of a plane from the ground?
If the planes are different, or separated, or at an angle to you, then it is IMPOSSIBLE for you to tell the relative altitudes when they are high in the sky. Just look at this: Or from the ground, with the planes at 30,000 feet. They look about the same height, right?
How is a plane moving when it is on the ground?
A plane sitting on the ground is moving with the surface of the Earth, and while it appears to us to be at rest, it is actually moving at around 1,000 miles an hour (the exact value depends on your latitude). When it takes off, it still has speed from sitting on the ground.
What’s the difference between the bottom and top of a plane?
If the planes are flying lower, then it’s still similar. If the top plane was flying at 20,000 feet, then the bottom would be at 18,285 feet, still nearly 2,000 feet apart, and looking pretty much the same to the naked eye. And that is with the same model of plane, directly overhead, and right next to each other.
