The Rogers Commission later determined the cause of the accident to have been the failure of the primary and secondary (backup) O-ring seals on <i>Challenger</i><span class="nowrap" style="padding-left:0.1em;">'</span>s right Solid Rocket Booster (SRB). The failure of these seals allowed a flamethrower-like flare to impinge upon one of two aft SRB attach struts, which eventually failed, freeing the booster to pivot about its remaining attachment points. The forward part of the booster cylinder struck the external tank inter-tank area, leading to a structural failure of the <a href="/wiki/Space_Shuttle_external_tank" title="Space Shuttle external tank">Space Shuttle external tank</a> (ET) – the core structural component of the entire stack. A rapid burning of liberated propellants ensued. With the structural "backbone" of the stack compromised and breaking up, the SRBs flew off on their own, as did the orbiter, which rapidly broke up due to overwhelming aerodynamic forces. The launch had been approved despite a predicted ambient temperature of 27 °F (−3 °C), well below the qualification limit of major components such as the SRBs, which had been certified for use only at temperatures above 39 °F (4 °C).<sup id="cite_ref-rogers-vol4-part7_5-0" class="reference"><a href="#cite_note-rogers-vol4-part7-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> Evidence found in the remnants of the crew cabin showed that several of the emergency <a href="/wiki/Personal_Egress_Air_Pack" title="Personal Egress Air Pack">Personal Egress Air Packs</a> (PEAPs) carried by the astronauts had been manually activated, suggesting that forces experienced inside the cabin during breakup of the orbiter were not inherently fatal, and that at least three crew members were alive and capable of conscious action for a period following vehicle breakup.<sup id="cite_ref-kerwin-letter_6-0" class="reference"><a href="#cite_note-kerwin-letter-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> "Tracking reported that the vehicle had exploded and impacted the water in an area approximately located at 28.64° north, 80.28° west".<sup id="cite_ref-daily-leader_7-0" class="reference"><a href="#cite_note-daily-leader-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Crew_fate">Crew fate</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=STS-51-L&action=edit&section=6" title="Edit section: Crew fate"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Divers from the <a href="/wiki/USS_Preserver" title="USS Preserver">USS <i>Preserver</i></a> located what they believed to be the crew cabin on the ocean floor on March 7, 1986.
