A flight attendant's primary job is to keep you safe — and they're trained extensively for any kind of emergency

Even though midair disasters like the one that happened aboard Southwest Airlines flight 1380 on Tuesday are rare, plane emergencies are a possibility when you fly.

After Flight 1380 experienced a major engine failure, along with a window failure, that resulted in a passenger death on Tuesday, Southwest's crew were commended for how they handled the emergency landing — and they have their extensive training to thank.

"By all accounts, the crew — both the pilots and the flight attendants — did an outstanding job," wrote Patrick Smith, a commercial airline pilot who runs the blog AskThePilot.com. "That is to say, they did exactly what they were trained to do, what they were supposed to do, and what they were expected to do."

It's understandable that the story would

But you may take some comfort in learning that airline crew on all airlines are trained extensively on how to handle any emergency — ensuring your safety is, after all, their primary role.

"People think we are just there to serve up Cokes and attitude, but we're fully equipped to save you and your loved ones in an emergency," Riley, a flight attendant with three years' experience, told Business Insider.

Other flight attendants say one of the most common misconceptions people have about their jobs — that they are simply glorified waitresses — is flat out wrong.

"Our job is dangerous, physically demanding, and laden with immense responsibility for the safety, security, and survival of our passengers," a flight attendant with 23 years' experience told Business Insider.

Here's how flight attendants know exactly what to do during a plane emergency:

Getting through flight attendant training is no walk in the park

Getting invited to the Delta flight-attendant training center, for example, is more difficult than getting into Harvard University. According to Delta, of the 150,000 people that applied to be a Delta Flight Attendant in 2016, only 1% made the cut. By comparison, the acceptance rate for Harvard's class of 2021 was 5.2%.

Making it through flight-attendant training is no picnic either, and flunking out results in not getting hired,

During the 2006 Travel Channel show "Flight Attendant School," Frontier's then vice-president of in-flight services and instructor Pam Gardner noted that one in three trainees never make it through Frontier training, either because they drop out or are removed for not maintaining academic requirements or meeting the standards of conduct. Throughout the docu-series, you see students ejected for showing up late to class or failing more than two exams.

"It's pretty stressful, and I think it's designed to be that way," Long said.

Flight attendants have six to eight weeks to learn everything there is to know about the plane, FAA and other safety regulations, and how to handle emergencies

Long recalls a time when her training was put to the test during a 747 flight to Frankfurt. "I was brand spanking new on this plane — and the cockpit had an alarm that told them there was smoke up in the crew rest," she said.

"So here I go running through the airplane with my fire extinguisher and another flight attendant and pulling out panels to where the pilot told us to go," Long said.

"Fortunately it was just a faulty alarm. But when you're thinking about fire over the Atlantic in a 747, it'll get that training out," she said. "It's down to you. It's not like they can land in the nearest airport."

Medical training covers all the bases

As part of Delta Air Lines' " target="_blank"Earning Our Wings" YouTube series, an instructor named Mallory said that on her very first flight as a flight attendant, she had a medical emergency on board. Luckily, thanks to her medical training, she knew exactly what to do.

"It's multiple hats wrapped into one," a flight attendant trainee named Cesar said in the video. "If something were to happen on board an aircraft, you are the doctor, you are the police officer ... you are the firefighter if need be. We have to be prepared for anything."

During medical and first-aid training, flight attendants learn all manner of skills, from using an AED to performing CPR on adults, children, and infants.

"These skills are just great life skills," a flight attendant trainee named Sharyl said in the Delta video.

During training, flight attendants learn how to evacuate a plane with half of the exits blocked within 90 seconds

Flight attendants learn emergency management in a flight simulator, where trainees begin by playing the part of the passenger, occupying the seats of the mock airplane.

When the simulation begins, "all of a sudden, the lights go out, and we're being told to put our head down and stay down and prepare for impact," a flight attendant trainee named Daniel said in the Delta video. "It was shocking."

As a voice telling passengers to "brace for landing" comes over the intercom, instructors bellow "Bend over," "Stay down," and "Stay seated" in unison, as flight attendants might during an emergency situation.

"We smoked out the cabin and started yelling our commands," an instructor named Mallory said. "They really get to see what as a flight attendant you do in an emergency."

Finally, they evacuate the plane using the emergency slide.

"It definitely makes your blood pressure escalate," a flight attendant trainee named Cesar said.

The Federal Aviation Administration requires Delta flight attendants to be able to evacuate an aircraft with 50% of the exits blocked within 90 seconds.

Flight attendants have to do water evacuation drills as well — even if they don't know how to swim

Flight attendants must get in the water to be able to pass the pool drill during training.

Luckily trainees have flotation devices, and the three trainees in Delta's video who didn't know how to swim were able to complete the drill .

"On pool day, I thought it would be pretty simple — I mean you float and you have to have a flotation device," a flight attendant trainee named Kacey said in the video. "I had no idea how many different things went into something that sounded so simple."

During the pool drill, trainees practiced pulling each other around the pool and into the emergency raft. "I was beat tired by the time that hit," Cesar said.

"I had no idea it would be that hard to climb into a raft," Kasey said.

The training never leaves flight attendants

During takeoff, United flight attendant Robert "Bingo" Bingochea told Business Insider his mind goes to a different place.

"You go through the different situations that can happen in your head," he said.

According to Bingochea, protocol for different emergency situations are embedded in flight attendants from day one of training so that, in an emergency, they don't have to think about it. "It's just there," he says.

And to supplement their training, flight attendants must refresh their skills every year

The crew-only areas inside airports often house computer stations and training areas so flight attendants can stay up to date and complete training modules, which they must do every year.
