I saw this and I had just listened to the interview on Camelot about the Black Budget planes and was especially interested in the triangular plane that could project the view above it (ie, stars) on the botttom of the fusalage to make it appear translucent to anyone on the ground.
This is all very interesting with taxpayer money. I remember when they released back in 2006 that Duke University was working on a special metal for military application that would bend light to make it invisible to viewing and to radar.
