EDWARDS AFB - NASA engineers are working on a means of training pilots in new methods to successfully fly and land airplanes in emergencies. The project, a joint effort with the Department of Homeland Security and United Airlines, as well as the National Aeronautics and Space Administration, is meant to study the effectiveness of using an aircraft's engines to control its flight when the usual flight controls are ineffective. In a technique known as throttles-only control, pilots of an aircraft in which the flight surfaces are inoperable instead use the aircraft engines to direct the airplane. For instance, increasing the...
