I have a couple of books on the SR-71. Brilliant plane. Is the fuel an issue? I understand it is a special blend that you cannot ignite even with an open flame.

Everything about the plane and the materials was new and exotic and a challenge to fabricate. They had periodic problems with titanium holes splitting and couldnt work out why. They eventually found out that in summer the city added chlorine (I think) to the water which made the metal brittle, so they eventually used distilled water.
