On Friday, April 6, experts blew up the old structure, but contrary to their plan, the tower collapsed on the library building.
"I simply do not know how it may have gone so bad," blasting manager Kenneth Wegge said, as quoted by NYP.
Policemen and rescuers were at the scene. According to them, no one was injured at the demolition site.
Officials are trying to find out what caused the silo to fall on the library building.
