The EAA AirVenture event brings out aircraft by the thousands, including Virgin's Eve, the Airbus A380, and Samson's Switchblade concept.
The odd-looking bird seen here is the Virgin Mothership Eve, the aircraft that will carry Virgin Galactic's SpaceShipTwo rocket aloft for a midair launch of tourists into orbit. Also known as the WhiteKnightTwo, "Eve" has a wingspan of 140 feet. The SpaceShipTwo will be mounted between the twin fuselages.
