NBC Gnews is reporting the NTSB is issuing immediate directives
[what are theirs called -- the FAA's are AD's] based on hypothesis
that the crossfeed somehow caused a static discharge. They say the
crossfeed pipe runs THROUGH the center fuel tank.

The directives are said to include adding cold fuel to the center
tank when on the ground, limiting AC use while taxiing, and possible
N2 injection.

The AC heat exchangers are UNDER the tank {That woudl explain how
the fuel got so hot.} and 800 was using them for 3 hours?

A) What are operational reasons to have the center tank empty vice
the wings? Is this a CG or loading issue?

B) Was 800 really in the takeoff queue for three hours? I'd assume
that while at the gate it was provided with ground based AC --true
on 747s?

C) To my unsurprise, Jimmy Kellstrom is said to still be seeking a
bomb.
