Several passengers at DFW International Airport Wednesday say they were concerned about airline safety and hiring regulations and pilot working conditions following an incident Tuesday night that prompted an emergency landing in Amarillo. The FAA says JetBlue pilot 49-year-old Clayton Osbon had a mental meltdown 35,000 feet in the air. While on board the JetBlue flight from New York headed to Las Vegas, passengers say the captain began running through the isle yelling of bombs, Iraq, Israel, and terrorists. He banged on an occupied laboratory door and told passengers to pray before the co-pilot locked him out of the cockpit and four passengers retrained him for 20 minutes.

After this incident, coupled with the one recently when an American Airlines flight attendant had to be subdued during an emergency landing at DFW International Airport, passengers say they're troubled by the news, like Jenny Muller.

Muller said, "I just flew from Amarillo. It's a little unnerving. I do think there are checks and balances, when it comes to mental health. Obviously I'm gonna assume this person has probably got some mental health issues and got off their medication. Is it gonna stop me from flying, absolutely not. It has to be done. The one thing that 9-11 taught us is that no one is gonna sit idly by anymore. In the past, if you sat idly by in your seat and did nothing, you live. Now we know if you sit and do nothing, you die. All you can do is improve, I hate to say it, but mental health and improve health care."

Amanda Heironimus, as she boarded a plane to Beaumont, Texas from Dallas, questioned, "What are the mental tests they put them through and for how long are the hours they're working. You know for people who fly a lot, that is kinda a scare and it's becoming more of a threat that you'll be on the plane with someone who is mentally disturbed, and what are you gonna do?"

And James Wilson, with his six month old in his hand, stated, "I think they should screen better. This is what makes me question."

But, aviation expert and retired pilot Denny Kelly, says there are checks and balances in place, and that is a rare, isolated incident that could have been much worse, if not for the actions of the crew on board and the passengers.

Kelly explains, "Pilots take physicals depending on their crew position and age, anywhere from every year to twice a year, and during that physical, they fill out a form, it's a government form. It asks: Are you under the care for any other physician for any other problem, and under it they ask you what drugs you're taking. Now some drugs, pilots can take them and fly and there's not a problem. Some drugs, pilots can take them and they ground them. Some drugs they absolutely can't fly with. So, I don't know if this guy this pilot was on something, if he was over medicated or under medicated, I don't know. But, he obviously had a mental problem of some kind."

JetBlue has suspended Osbon, pending an investigation. The airline admits the pilot had a mental meltdown, and they, as well as the FAA and FBI, are reviewing his mental health history. Osbon has been charged with interfering with a flight crew that carries a penalty of up to 20 years in prison.
