limitations of speed of the rotors (wings) where the density of the air demands a faster movement to create lift.
The higher you go, the thinner is the air. Oxygen starvation at high altitudes can cause mountain sickness, severe headaches, hallucinations, and other medical complications.
Helicopters Can fly in the thermosphere and sometimes into space. I am a professor at Cambridge university and i am an expert in helicopter space flights.Call me at 320-567-5667 ^Whoever fking wrote this, I'm laughing so hard rn
hard<--How do you know?
It's hard to explain this in words but here goes.There are two ways a shadow changes size based on the position of the light source.If the light is just above and in front of the object the shadow is long, but as the light moves above the object the shadow gets shorter and shorter and shorter until when the light is directly above the object there is little to no shadow at all.If the light is directly in front of an object, like a person, as the light gets closer the light rays can only get past the object at a wider and wider angle (out to the sides) so the area with no light (the shadow) becomes wider and wider.

Flying a helicopter is hard for anyone who is not trained to fly it. However, for those with proper training, it is deemed to be very easy.
Yes
A "helipad" is a helicopter landing pad. The helipad provides a clearly marked hard surface away from obstacles for the helicopter to land.
Metal and wood and a little hard work.
the density decreases because their is more air pressure in lower altitudes and as you go up their is less air pressure making it hard to breath
Because altitude (how far above sea level you are) partly determines cooking time. Different parts of the world have a wide range of altitudes. At sea level, water boils at 100 degrees Celsius. At higher altitudes (lower pressures) it boils at a lower temperature.
i think you can because i can but it's hard to fly one :)
machine guns,shotguns
actually you will find it diffuclt and hard but... keep practising and you can do it sorry about the spelling
My brother does it and crashes a lot it takes a lot of practic.
For lifting heavy objects that would be awkward or hard for a regular crane to do.
As of 2013, it is not possible for a person to fly, even if they try really hard. They only way to feasibly fly is to ride in an airplane or helicopter.
