Heading up this engineering A-team is aviation genius
Clarence "Kelly" Johnson. The project is classified black,
above top secret. The plane is christened the SR-71. Building the SR-71 is the greatest
engineering challenge in aviation history. The 500-degree heat
generated at cruising speed means the cockpit windshield
will melt lead. Tests show that, at Mach 3,
the plane expands several inches as it heats up
under extreme temperatures. Everything must be built from scratch
