According to New Scientist, the video comes from Bob Karman, a nurse whose daughter works at the publication. Karman filmed the launch from the Orlando, Fla., airport where he was with his family after a trip to Disney World.
In the video, a group of spectators are initially unaware of the events going on before their eyes. Moments later, though, it's clear something's gone wrong.

This isn't the only home video of the launch. In 2010, footage from a neighborhood in Winter Garden, about 80 miles from the Kennedy Space Center launch site, surfaced. At the time, the Guardian wrote that "it is believed to be the only amateur film in existence of the world's worst space disaster."
The launch was also broadcast on live television.
Tragedy struck the shuttle program again in February 2003, when the space shuttle Columbia was lost upon entry over Texas. That accident also claimed the lives of all seven crew members.
NASA's Space Shuttle Program flew 135 missions between 1981 and 2011.
The remaining space shuttles in the fleet -- Enterprise, Discovery, Endeavour and Atlantis -- are being prepared for retirement and will be put on display at museums throughout the United States.
