Uploaded by @tech, the clip elicits some engaged comments from viewers. “Is there anything more iconic than the SR-71 Blackbird?” wonders @jonnylee022. “Can’t believe nothing has gone faster for 46 years.” “Many aircraft have gone faster since, but they were mostly experimental, from the X-15 up to the more recent Aurora,” writes @slydermac. “The speed accomplishments were actually achieved in the late 1960s,” notes @writeroftomes3. “I was assigned to a USAF base with a TS clearance where the jet flew out of.” User @alexandersvarte1 has a thought about the changing priorities for a contemporary challenges. “We can make something faster, just we don’t have a need for it,” he says. “Used by both NASA and the USAF, the SR-71 was developed in the 1960s for reconnaissance missions,” writes Jetify on its Website. “The last SR-71 was retired in 1999 by NASA since many reconnaissance roles are now undertaken by satellites.” “As well as flying fast, the Blackbird was capable of flying high for sustained periods,” Jetify adds. “While some jets can climb high, many cannot cruise at high altitudes, but the SR-71 could easily fly at heights of 25,000 metres, making it perfect for reconnaissance from a safe distance.” At one time, the SR-71 flew from New York to London in 1 hour and 54 minutes. This was faster than the Concorde, which at the time took 2 hours and 52 minutes. Recommended for you
