"I heard it and felt it in the ground," Smith told the Louisville Courier Journal, part of the USA TODAY Network. "I tell you what, it grabbed your attention."

Karen Roberts, assistant community director at the Axis at Lexington, was showing off an apartment to a prospective renter when she heard the explosion. Tenants at the 300-unit Clifton complex rushed to their balconies to see what happened, she said.
