NASA to Test 'Scramjet' Aircraft

NASA plans to test an aircraft this weekend designed to fly seven times the speed of sound, using an innovative engine called a "scramjet." The test is part of an effort to develop missiles that can reach any target on Earth within two hours, and spacecraft that can transport people and cargo more cheaply. NPR's David Kestenbaum reports.
