What's the greatest mystery about #WTC6?

1) Two 10-story craters in 8-story building?
2) Explosions at same time "second plane" hit?
3) Collapsed before either tower?
4) The missing gold?
5) Tritium in basement 55x normal background level?
6) The fact that nobody talks about it?

WTC 6 (aka US Customs House) was 8-story building located between #WTC1 & #WTC7. It had a large vault (15m x 15m) in its basement that was used by the fed agencies in #WTC6 & #WTC7 and reportedly held the gold of the Bank of Canada.

Christopher Bollyn confirmed from raw CNN video footage that a huge dust cloud (seen above "BREAKING" in photo) coming from a mysterious explosion at #WTC6 occurred at 9:04 a.m. on 9/11 at exactly same time as second plane crashed into the South Tower.

#WTC6 was evidently destroyed before either tower collapsed. Here, the heavily damaged building can be seen as the South Tower is demolished.

Kurt Sonnenfeld, official FEMA videographer, visited #WTC6 basement post-9/11 & saw the giant vault, which held crucial evidence, protected info & Bank of Canada gold, had been broken open & emptied BEFORE attack, would have taken large trucks & many hours

Tritium levels in #WTC6 basement 55 times greater than background 11 days after 9/11 even after a million liters of rain & firehouse water had diluted the samples, providing conclusive evidence of a thermonuclear fusion reaction at Ground Zero on 9/11

I should add that miraculously no one was killed in the #WTC6 explosion because all 800 workers in the building were evacuated within 12 minutes of the first plane striking the North Tower (which caused a lot of debris to rain down on the roof of WTC6).

"If both towers are still standing & smoke is being blown away from the towers, what is this huge plume of smoke approximately 50-60 stories high rising from the Trade Center area?" It's the explosion that destroyed #WTC6, the building no one talks about!
