1st place: Scaled Composites Stratolaunch Carrier Aircraft – span 117 meters

It's photographed resting under its mothership, White Knight Two.

The VSS Unity will be attached under a carrier plane, dubbed WhiteKnightTwo.

The rocket plane is shown attached to the White Knight Two carrier airplane.

Other spaceships and a second carrier aircraft will also be created.

It was carried into orbit by a Pegasus rocket that was launched from a jet aircraft.

This is an aircraft carrier to be used for space tourism.

The plane is carried to an altitude of around 45,000 feet by a larger dual-cabin carrier aircraft called WhiteKnightTwo.

A major disadvantage of a parasite aircraft was that it reduced the payload capacity of the carrier aircraft.

It has even been claimed that a new mother/daughter combination like the A-12/D-21 has been flown, known as the Super Valkyrie.

A mothership plane is one which is used to carry another vessel, typically a rocket, to higher altitudes before it launches.

Developped during the 70s it should have been launch from a supersonic plane (SPIRAL project).

It is carried to a height of about 50,000 feet (15,000 meters) by a large aircraft called WhiteKnightTwo.
