It was a very well kept secret for a short period of time, but Paul Allen, co-founder of Microsoft and original financier for SpaceShipOne during the X-Prize competition, has been working with Scaled Composites to create the largest aircraft ever.
The secret came out during an expose on the unfortunate loss of SpaceShipTwo during a routine test that resulted in the death of pilot Mike Alsbury. As part of the filming, Scaled Composites allowed partial viewing of the aircraft named, StratoLaunch.
The six-engine aircraft will be tasked with launching rocket-propelled satellites into space. Orbital Industries is one such contractor that has already partnered with the Stratolaunch program.
In March 2013, a 103,257-square-foot hangar was built to house the huge aircraft which is expected to make its first flight in 2016.
