SR-71 leading edge

Gary — 4/23/2005 11:55:03 PM (archived)

Titanium was used for the SR-71's leading edge. Titanium has flight heritage. Aluminum powder burns intensely and is an ingredient in solid rocket fuel and thermite.

        Correct... Titanium can not be used on a reentering vehicle's leading edge - Gary - 4/24/2005 2:43:15 AM
