What is the full name for the blackbird airplane?

SR-71 Blackbird. This airplane is used in the army. They are made out of titanium and titanium is the second strongest substance on earth(strongest is diamond). They are made like that because they can fly faster than a missile so they risk getting hit and can fly 85,000 ft (16 miles) up. Only a space ship can fly higher than that. They are very fast to. They can fly 33 miles in one minute. They can get up to over 1,000 mph. That is some of what I know about this plane.
