"Thermite contains its own supply of oxygen and does not require any external source of air. Consequently, it cannot be smothered and may ignite in any environment, given sufficient initial heat. It will burn well while wet and cannot be easily extinguished with water, although enough water will remove heat and stop the reaction. Small amounts of water will boil before reaching the reaction. If thermite is ignited underwater, the molten iron produced will extract oxygen from water and generate hydrogen gas in a single-replacement reaction. This gas may, in turn, burn by combining with oxygen in the air."

Molten metal ? Anyone ever seen a large quantity of aluminum being melted ? I have .
It is definitely in a molten state when it is smeltered in large quantities , and remains red hot for weeks .

How about you show some actual research that you might have done to support your assertion ?
History
The reaction was first used for the carbon-free reduction of metal oxides. The reaction is highly exothermic, but it has a high activation energy since strong interatomic bonds in the solids must be broken first. The oxide was heated with aluminium in a crucible in a furnace. The runaway reaction made it possible to produce only small quantities of material. Hans Goldschmidt improved the aluminothermic process between 1893 and 1898, by igniting the mixture of fine metal oxide and aluminium powder by a starter reaction without heating the mixture externally. The process was patented in 1898 and used extensively in the later years for rail track welding.

You can't just randomly mix rust and aluminum and expect to produce thermite, this is an old ridiculous claim.
If I were to throw flour and water in the air should I expect a cake to appear?

Just because particles of iron-oxide and aluminum were found in the dust samples DOES NOT constitute nano-thermite .
