Boeing subsidiary Aurora Flight Sciences has wrapped up the conceptual design review for a new high-speed X-plane that can liftoff vertically. So far, the development has been a success, and the concept has been chosen to continue work on a preliminary design review. 

The X-plane is being developed for DARPA's SPRINT program, which stands for Speed and Runway Independent Technologies. The project aims to design, build and fly an aircraft that is fast and doesn't rely on a runway for takeoff and landing.
