Reports on the possibility of developing an aircraft that can fly faster than the speed of sound without generating a sonic boom, using the supersonic biplane design. Basis of the supersonic biplane design developed by professor John Ffowcs Williams of Cambridge, England; Details on how the sonic booms are produced; Views of aviation analysts on the market for business jets; Award received by Williams for his contribution to researching the properties of sound.
