Speaking to the AP, Michael Schiavone, 37, was at his home in Mayfair on Friday when he heard a loud bang, and his house shook. He said it felt like a mini earthquake, and when he reviewed his home security camera footage, it appeared as though a missile was descending.

NTSB investigators found the Learjet 55's cockpit voice recorder Sunday. The agency said it was 8 feet down at the site of initial impact. The death toll is 7, with 22 injured.

The plane had been on a medical transportation mission to Mexico, carrying a child patient, her mother and four crew members.
