Atypically, Burt Rutan of Scaled Composites has preannounced that SpaceShipOne will fly on 6/21, trying to become the first privately built craft to break the 50 mile altitude that is set as the edge of space. Note that if the launch comes off, it will also have been a nine week cycle time since the last flight (the X Prize requires six). Maybe we're finally on a real learning curve.
