Letter: ‘Qualified Success’ Sells Pegasus Short

by

I recently read your editorial “Don’t Shortchange ALASA” [Nov. 21, page 18], with which I generally agree. However, I was dismayed by your description of our Pegasus program as the “one qualified success” of the U.S. Defense Advanced Research Projects Agency (DARPA) in space launch vehicles and by the inattention to the historical facts of its development and operations. Contrary to your interpretation, the Pegasus program, as measured against virtually any common space industry benchmark, has been an “unqualified” success for more than two decades.
