For a week or so every summer, Wittman Regional Airport in Oshkosh, Wisc., becomes the
destination for aircraft enthusiasts. That's because it's the venue for the annual convention of the Experimental Aircraft Association. The group's name notwithstanding, the EAA AirVenture
show is as much about aviation heritage as it is about cutting-edge machines. This year's event began Monday, and it runs through the weekend.
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.
