STS 51-L Launch 01/28/1986 filmed from TV Van #2 at the Shuttle Landing Facility (SLF) on site at Kennedy Space Center. This video was made from a copy of a ¾ videotape received from NASA under provisions of the Freedom of Information Act. This video is not copyrighted. Its wide distribution is welcome as an aid in understanding the experience of watching the disaster unfold in person. STS-51-L crew: Dick Scobee, Michael J. Smith, Ronald McNair, Ellison Onizuka, Christa McAuliffe, Gregory Jarvis & Judith Resnik. The shuttle was designed to withstand a load factor of 3 (or 3 g), with another 1.5 g safety factor built in. The crew cabin in particular is a very robust section of the shuttle because of its design and construction of reinforced aluminum. During vehicle breakup, the crew cabin detached in one piece and slowly tumbled into a ballistic arc. NASA estimated the load factor at separation to be between 12 and 20 g; however, within two seconds it had already dropped to below 4 g and within ten seconds the cabin was in free fall. The forces involved at this stage were likely insufficient to cause major injury. At least some of the astronauts were likely alive and briefly conscious after the breakup, as three of the four Personal Egress Air Packs (PEAPs) on the flight deck were found to have been activated. Investigators found their remaining unused air supply roughly consistent with the expected consumption during the 2 minute 45 second post-breakup trajectory. While …
