Tests conducted aka Two planes Virgin VSS Enterprise spaceship on May 4, 2011 and then a huge success. Virgin Galactic's suborbital vehicles, commercial company, founded billionaire Richard Bronson will be used to bring tourists to the limits of gravity of Earth.

One of the sophistication of these aircraft is the ability to fly like a feather. The method was designed by Burt Rutan is the biggest innovation is integrated on Spaceship Two. The position of flying like a feather that can be achieved when the plane turned onto the tail of about 65 degrees. Position it produces a very stable aerodynamic shape while creating tremendous resistance that can brake the aircraft upon entering Earth's atmosphere.

Even so, the airframe does not become too hot because it is made of extremely lightweight material. Additional thermal protection to minimize the heat generated due to friction with the atmosphere can also be avoided.

Pilots can even release the hand from the handle control of the aircraft when the aircraft is in proper flying position. Because, at that position the aircraft can fly with a very stable and pass through the atmosphere are naturally just by relying on an aerodynamic shape. This is a security feature that is very beneficial because the pilots did not have to maintain the aircraft position on a particular slope or must rely on computer systems.

In a video released by Virgin Galactic Spaceship Two aircraft seen being dropped from aircraft at an altitude of 51,500 towing WhiteKnightTwo feet. Although visible light as a feather floating by, the plane slid down with a speed of 15,500 feet per minute. The resulting aerodynamic prisoners managed to reduce the speed of the aircraft with very significant.
