How did the Pentagon get its unusual shape? How many people work at the Pentagon? What covert intelligence gathering organizations operate within the military compound--and how are their secrets protected? What top-secret information was compromised from the attack on September 11th? How quickly did the building and its tenants get back to business as usual? For seven decades, the Pentagon has been an icon of American strength and military excellence. But more impressive than the building itself are the secrets held there...until now.
