That's how long NASA's space shuttle Challenger was in the air before an O-ring failure turned a routine mission into space into a tragedy on January 28, 1986.
Twenty-five years after NASA's first fatal in-flight accident, the memory of the Challenger disaster is still strong.
CNN's John Zarrella was at Kennedy Space Center to cover the launch - the first from NASA's new launchpad 39B. "I just remember seeing the cloud of smoke and what looked like fireworks coming out from the vehicle," says Zarrella. "We were all just looking at each other wondering 'OK, what's happened here?'"
CNN, still in its early years, was the only network to carry the launch live that Tuesday. Among those tuning in were children in classrooms across the country, watching what was to be a milestone: Christa McAuliffe, the program’s first teacher in space, lifted off as a member of the crew.
An investigation later revealed a rubber "O-ring" seal on one of Challenger's solid rocket boosters had failed because of unusually low temperatures. This caused a leak of highly explosive gases, which ultimately led to a catastrophic explosion at 46,000 feet.
It would be almost three years before the space shuttle program would return to flight. NASA wouldn't experience another disaster until the loss of space shuttle Columbia in 2003, when a hole in the shuttle's heat shield caused it to disintegrate on re-entry to Earth's atmosphere. The Columbia disaster would ground the shuttle program for another two years.
Seven lives were lost in the Challenger explosion: Dick Scobee, commander; Michael J. Smith, pilot; Ellison Onizuka, mission specialist; Judy Resnik, mission specialist; Ron McNair, mission specialist; Gregory Jarvis, payload specialist; and Christa McAuliffe, payload specialist and teacher.
