The controlled demolition of WTC 7 certainly made one heckuva powerful hammer!
Not really - as has already been pointed out, data was recovered from hard drives in the WTC towers. The answer that LeetMan is looking for here, is that the worst possible way to try to hide your data is to fell the building that houses it.
By the way, there is now a great free program for Windows PCs to encrypt your hard drive. If someone stole my laptop, they would get a hard drive filled with data indistinguishable from randomness (unless you have the password). The program is TrueCrypt, and I highly recommend it for all NWO employees with laptops: http://www.truecrypt.org/
