A SpaceX Falcon 9 rocket has exploded at Cape Canaveral
In looking at failures, asking "What changed (was different)" in this case, is one generally useful approach...<p>Based on previous comments, the most likely failure scenario seems to be related to the new use of super-cooled LOX - and I have to ask, was the temperature at the pad, at the time of the launch, significantly higher than during previous launches involving super-cooled LOX?  If so, is there a possibility that the higher temperature differential could have been a contributing factor in the cause of the failure?<p>(Kind of the exact opposite of the case of the Challenger, where low temperatures were a critical causal factor of the failure)
