5 Things to Know This Morning

— -- Your look at the five biggest and most buzz-worthy stories of the morning.

1. Watch Deaf Minnesota Infant Hear His Mom for the First Time

A 9-week old infant looked surprised when he heard his mother's voice clearly for the first time, thanks to hearing aids.

Elijah Cook was born profoundly deaf in his left ear and able to hear only 75 decibels on the right side, according to a description by his mother on her YouTube page.

His mother, Ahavah Cook of Andover, Minnesota, said in a post for the Children's Hospitals and Clinics of Minnesota that she and her husband, Jason Cook, knew it was a possibility that Elijah could have hearing loss because both of their fathers and mothers were deaf. Additionally, Jason had no hearing in one ear. But they were hoping for the best.

2. US Military Unaware Gyrocopter Violated DC Airspace

The United States military says it was unaware that an aircraft had flown into restricted airspace over Washington, D.C., Wednesday and was only alerted of its presence after it landed.

Just before 2 p.m., Douglas Hughes was arrested after landing his gyrocopter on the West front of the United States Capitol building, said U.S. Capitol Police.

The United States Northern Command and North American Aerospace Defense Command (NORAD), the military organizations responsible for protecting the capital region airspace, say they never saw it. “There was no NORAD involvement,” said spokesman Michael Kucharek. He deferred questions about who may have detected it first to the U.S. Capitol Police and the Federal Aviation Administration (FAA).

3. Search Area for MH370 to Expand If Plane Not Found

Authorities plan to expand the search zone for missing Malaysia Airlines Flight MH370 if the plane is not located in the coming months.

Malaysian Transport Minister Liow Tiong Lai, Australian Deputy Prime Minister Warren Truss and Chinese Transport Minister Yang Chuantang appeared at a press conference Thursday to discuss the search for the plane, which went missing in March 2014 with 239 people on board.

Dan Price, the CEO of Gravity Payments in Seattle, has touched off a national debate over his plan to pay all of his workers a yearly salary of at least $70,000. But where did that figure come from and what's behind it?

The number, the CEO said, comes from a 2010 Princeton University study by economist Angus Deaton and Nobel-prize winning psychologist Daniel Kahneman and published in the Proceedings of the National Academy of Sciences. In the study, the researchers analyzed the answers to questions about income and well-being from more than 450,000 Americans polled by Gallup and Healthways.

5. Kenny Loggins Finally Finds the 'Danger Zone'

Three decades after recording the smash song "Danger Zone," singer Kenny Loggins finally discovered his own personal danger zone Wednesday, after a Marine Corps helicopter landed on a southern California beach.

The CH-53E Super Stallion landed in Solana Beach after a low oil-pressure indicator light went on in the cockpit, authorities said – a spectacle that drew stares and attention from nearby beachgoers, including Loggins.

“Lo and behold, I walk down there and I say, ‘You’re in the danger zone!’” Loggins said in a video he filmed while standing near the helicopter. “We literally are.”
