we have a person here who was involved in the building of it

said it would take a lot of fuel

and that is about a billion dollars up in smoke

So look... cardboard boxes ARE fuel.

But a plant that big, even cardboard, starting from a single source, many areas would be burnt out by the time others lit...cardboard burns fast.

But no... it looks to have ALL gone up at once. As in hundreds of ignition points or, massive quantities of accellerant.

Doubt it. The items burned are furniture (indoor and outdoor), matresses, rugs, and other large items.
