The latest news from around North Texas.
Since 2018 more than 4,000 crew members have been trained in the Dallas area.
Taught by certified Air Marshal instructors, flight attendants learn tactical ways to defend themselves in case they are attacked by a passenger.
"We feel it's very vital for them to feel comfortable in the incidents they are dealing with on the aircrafts, the various assaults, and things of that nature," Federal Air Marshal Service Dallas Supervisory Air Marshal in Charge Byron Irby said.
According to the FAA as of October 12, 2001, there have been 4,724 reports of unruly passengers. 3,433 mask-related incidents have been reported.
With incidents on the rise, the course teaches physical moves and more.
"It's not just about putting hands on someone,” Irby said. “It's to help them get through a situation that may call for them not to put hands on an individual. But if they do in turn have to defend themselves, we want them to be prepared."
Being prepared is important. But they hope they never have to put these skills to the test.
"Our main goal is to keep peace on the plane and not increase any hostile situation," Laban said.
"I've never had to get physical with a passenger and it's not something I want to do," Yvonne said.
The TSA said these classes are available to all flight attendants free of charge. The classes are voluntary.
Assaulting or threatening a member of a flight crew is a federal crime. You could face civil penalties, criminal fines or imprisonment.
