There has been published speculation, based on unidentified sources, that the finger of flame either burned through the fuel tank wall and ignited its huge supply of liquid hydrogen, or that it set off the destruction mechanism by lighting a primer cord...
After the initial blast, the slow motionvideotape replays showed an explosion of the hugeexternal fuel tank, which carried half a milliongallons of super-cold, super-volatile liquidoxygen and hydrogen. Challenger, dwarfed by thefuel tank, burst into pieces which rained into theAtlantic for 45 minutes...
