Pointless speculation, I know, but I can't help wondering that had there been a Flight Engineer as part of the crew, would the fire still have taken such a fatal hold?
I don't think it's pointless, esp as I raised this in an earlier accident thread, maybe this one. However, it's a matter of economics, really ie the cost of more crew vs the number of passengers who will be taking more risky transportation methods, such as drivin--in the US, at least.
