What happens when you mix the convenience of a 737, the speed of Concorde, the efficiency of an Airbus, and the luxury of first class together? You get a Dart (The plane, not the actual dart and dartboard) The Dart is optimized for supersonic flight. From the engines (equipped with bumps that slow down the incoming air) to the unconventional, but effective wing shape. The Dart might not have the greatest capacity, but it definitely is a big step in air travel.
