Glad to hear the crew is OK, and sounds like they did an outstanding job with the emergency. Funny how fire motivates humans.
I (along with everyone I'm sure) will be very interested to hear if the fire was caused by dangerous goods. In my experience properly packaged, labeled, and declared Dangerous Goods are safe....it's that UNDECLARED shipment that will kill you.
The obvious question is how do protect against the undeclared illegal shipment? This is an area where the need for profit is in direct competition with the need for safety.
If there is an upside to this event, maybe it means another 747-400 hull
