Next. As for huge sewer pipes - no way. The White House is only about 30 ' above the Potomac River. There is not enough "fall" to carry sewage away. Did you know that Constitution Ave. was once a "Drainage Canal"? It still is. The Canal is covered over and is now used to dispose of Snow when necessary
We can debate for hours on how many tons of explosives would be needed to destroy the White House, and how to get it inside, and hide it. - when there is no need, when I can formulate a plan to do it cheaper and quicker, with a "Sub-terra". They didn't have dynamite in 1865 so they would need more barrels of gunpowder to do the same damage.
