Helicopters

The combat range of most Chinooks is 450 miles

Helicopters are built, not spawned.

Planes cannot land straight up and down

Yes, many have done that

No, there are many more planes flying for longer periods than helicopters.

In 1995, $11.3 million US dollars.

Originally to take off and land where there were no runways.

That was the Vietnam war

Then you would have total chaos in the skies.

An air ambulance helicopter is generally the same as an ordinary helicopter except for the fact that it is equipped to save lives just as a regular ambulance is equipped. Air ambulance helicopters must have the medical supplies necessary to save lives.

In 2009 more than 2100 people!

It is one of the main controls.

I can think of chopper copter heli helo whirlybird and evem windmill

That's what they are good at.

Aircraft do have propellers , unless they are jets.

The rotor and rear propeller are turned by the transmission connected to the engine

Yes, helicopters fly high when on long journeys.

It is called the rotor.

An attack helicopter is best for attacking targets and a utility helicopter is best for carrying troops and supplies.

Aircraft and helicopter sales are NEVER that simple !They almost always involve spare parts, more engines, options in weapons and comms. The latest sale of Chinooks was to Australian Army who paid just over $500 Million USD for 7 CH47 F's. -The deal also included 2 full Simulators and many spare parts.

You will have to define that in a way easier to understand.

Some large helicopters use 'drogue and hose' refuelling

The front of the main rotor is tilted down

The size and shape define what the rotor will lift.

Planes have large wings, Helicopters have rotors
