An aeroplane generates lift to counteract the gravity by the difference of the air speeds on the two sides of its wings. The top side of a wing is cut with greater curvature than the bottom side causing the airflow path to be longer and the air speed higher on the top surface. As the side-way speed of a laminar air flow gets faster, the vertical pressure drops. And when the top side of a wing has pressure drops more than does the bottom side due to the difference in laminar flow speeds a lift force is generated--think aerodynamics.

The jet engine may be replaced by a rocket engine on an aeroplane to not need oxygen in the ambient. However, going too high up in the atmosphere, the air density gets too thin and the lift factor decreases so that an aeroplane cannot escape the atmosphere and hence cannot get into space. Also, there is no air and hence no aerodynamic lift in space; that means the wings and rudder planes cannot steer the spacecraft in vacuum as does the apogee-kick jet engines.

As I understand it, there are several factors:

One, you need a certain amount of thrust to penetrate beyond the lower layers of the stratosphere, or whatever layers you need to rise above;

Two, there will be less oxygen, so:

a) this vital ingredient will be in short supply for a slower speed aeroplane.

b) a human being piloting the plane would need a more complicated life support system than is provided here to date on private space exploration vehicles.

An "Airplane" uses an internal combustion engine (jet or prop), this would be tough to use in space since their is NO O2 to support "Combustion", Rocket engines have their own O2 supply, usually in the form of some sort of hydrogen peroxide, so combustion can be completed in an atmoshere void of O2.

A jet cannot fly high enough to get out of the atmosphere. Jet engines need air to burn the fuel.

nicely it quite is accomplished , that could require huge photograph voltaic panels.Even todays satellites orbitting around earth get maximum of their potential from photograph voltaic panels fittend on them, yet sending to it in an orbit could require huge volume of photograph voltaic potential to be tapped and switched over to electric potential.

Probably because they are moving at like 500 miles per hour and if they slowed down to mess with a sattelite, they would start to fall from the sky.

an aeroplane is not equipped with the (not sure) covering around it that reduces friction when exiting the atmosphere.
