(INDIANAPOLIS) - The company performing the implosion of Keystone Towers says both towers will come down at the same time Sunday morning.
Advanced Explosives Demolition Owner Lisa Kelly says they're using 750 pounds of dynamite-like explosives to bring the buildings down. Kelly says the explosives will be planted on various floors of the towers.
Once detonated, Kelly says the buildings should come down in about fifteen seconds.
