Big Hairy Ian writes "An aircraft that resembles a four-point ninja star could go into supersonic mode by simply turning 90 degrees in midair. The unusual 'flying wing' concept has won $100,000 in NASA funding to trying becoming a reality for future passenger jet travel. The supersonic, bidirectional flying wing idea comes from a team headed by Ge-Chen Zha, an aerospace engineer at Florida State University. He said the fuel-efficient aircraft could reach supersonic speeds without the thunderclap sound (PDF) produced by a sonic boom — a major factor that previously limited where the supersonic Concorde passenger jet could fly over populated land masses."
