At 85,000 feet, it could outrun missiles, literally flying faster than explosions behind it. When it was retired in 1990, it didn’t slow down. On its final flight to the museum, it broke four world speed records, including Los Angeles to Washington, D.C. in just over an hour. #TheWarRoom #SR71Blackbird #ColdWarTech #fblifestyle | The War Room | Facebook
