That was the way I recall it,  the vent system.  The 747 basically has the 
same type vent system by Boeing.
So,  possibly the vent system was the source of the Center Tank explosion,  
but the question is,  what was the ignition source that used the vent system?
I've miss placed your local phone number, again please.
