well,the 2 that crashed into the WTC towers probably wont be able to be recovered in tact due to the explosions. and if they were able to be recovered, it would help alot,but what i didn't understand is who was the genius that was watching the radar when they got in range that the radar COULD pick it up w/out the thingie that transports signals to the ground control thing place. because the airport for manhattan was only like 10 miles away and the airport's radar can pick up any moving object within a 40 mile radius in the air.so they could have saved a few hundered lives more than what they did.
