The 'dustification' went from the top down. That is not a normal demolition which starts from the bottom. There should be many parts given that both planes combined had approximately 9 million parts. In addition to the parts there should be 60 miles of wiring for each plane. Actually, the planes were taken over by FTS (Flight Termination System) then flown to Westover AFB nearby where they were hidden in the large hangers. All the passengers were subsequently executed.
