UPS in the 81st fllor ao WTC2? NIST answers

[Henry62]

Hi guys,

I received an answer from NIST about ups in the 81st floor of WTC2.

I wrote in my blog an article about lead batteries in the South Tower.
This is the link to my article:

UPS on the 81st floor of WTC2? (http://11-settembre.blogspot.com/2007/02/ups-on-81st-floor-of-wtc2.html)

Now I receive this email from Mr. Michael Newman Spokesman, NIST WTC Investigation:

Re: Question about UPS in WTC2



Enrico,

Modifications were made in 1991 to reinforce the 81st floor of WTC 2 in an area occupied by the United Parcel Service.

Modifications were made in 1999 to floor 81 in an area of the floor occupied by Fuji Bank to accommodate the weight of an uninterruptible power supply.

Both of these modifications are documented in the section of the NIST WTC Investigation Report known as NCSTAR 1-1C (go to http://wtc.nist.gov/NISTNCSTAR1-1C.pdf).

What is perhaps confusing is that both modifications were made to areas where there are two-way trusses (the corners of the building) and the acronyms (UPS for "United Parcel Service" and "uninterruptible power supply") are the same.

However, these modifications were made eight years apart for two different tenants, so there is no link between them.

I hope this answers your question.

Thank you,

Michael Newman Spokesman, NIST WTC Investigation

This is the first time NIST speaks of an ups ("uninterruptible power supply")area in the 81st floor of WTC2.

Thanks,
best wishes from Italy,
Happy Easter,

Very interesting, thanks.

Too bad they didn't discuss whether this involved the kind of batteries you mentioned, and whether they could have contributed to the molten drippings in that vicinity.

I've never heard of a large-scale UPS using any other kind of battery. (And backup generators are never referred to as UPSs.)

I guess someone could take the question to Fuji Bank, though.

Great work, Henry62. I was impressed by your original article and have always thought it very likely correct. Congratulations on getting a key confirmation supporting your conclusions.

Respectfully,

exactly, plus the fact that they had to reinforce the floor would also indicate a lead acid battery

Splendido, Enrico. :)


Thank you for sharing the results of your inquiries. I thoroughly enjoy reading your work and it's nice to see this piece of confirmation in support of your hypothesis on the issue of the UPS batteries. Splendido, indeed.

Certainly it indicates TONS of battery of some sort. And with that comes a lot of chemical energy no matter what type of battery we are discussing.

Not to mention an enormous amount of sulphur to contaminate left over welding fume that got shaken out of the nooks and crannies of the cores when the buildings fell.
