"He's fine," Fire Department Capt. Mark Bridge said. "There's no danger to him."
He said the cranes' bases were stable and that investigators didn't believe they were in danger of falling over.
Diane Stewart, who lives near the construction site, said she heard the collision while out for a walk.
“I heard a crash. It was like pipes falling,” Stewart said. “The police, first-responders were here in minutes.”
