Officials say no survivors are expected after an American Airlines flight with 64 people onboard collided mid-air with a military helicopter Wednesday evening.

Ryan O'Hara, 29, was the crew chief of the Black Hawk helicopter that collided with the passenger plane, according to CBS News. He leaves behind a wife and one-year-old son, his local Reserve Officers' Training Corps (ROTC) program said in a social media post confirming his death.
