Recent aviation disasters and close calls stoke fears about the safety of flying

That's not to mention the time earlier this month when a Japan Airlines plane clipped a parked Delta plane while it was taxiing at the Seattle airport, or the security concerns that arose after stowaways were found dead inside the wheel wells of two planes and aboard two other flights. In addition, a United Airlines plane caught fire during takeoff at the Houston airport and a passenger opened an emergency exit door on a plane while it was taxiing for takeoff in Boston.

So of course people are wondering whether their flight is safe?

What happened in the worst cases?

The Jan. 29 collision between an American Airlines passenger jet and an Army helicopter killed everyone aboard both aircraft. It was the deadliest plane crash in the U.S. since Nov. 12, 2001, when a jet slammed into a New York City neighborhood just after takeoff, killing all 260 people on board and five on the ground. After that, there hadn't been a deadly crash of any kind involving a U.S. airliner since February 2009.

Earlier this month, 21 people were injured Feb. 17 when a Delta flight flipped and landed on its roof at Toronto's Pearson Airport. Everyone survived that crash.

Crashes are more common involving smaller planes, like the single-engine Cessna that crashed in Alaska on Feb. 6, or the two small planes that collided in Arizona on Feb. 19. Ten people including the pilot were killed in the Alaska crash, and two died in the Arizona one.

A medical transportation plane crashed in Philadelphia on Jan. 31, killing the six people onboard and another person on the ground. That Learjet generated a massive fireball when it smashed into the ground in a neighborhood not long after taking off from a small airport nearby.

How worried should I be?

Fatal crashes attract extraordinary attention partly because they are rare. The track record of U.S. airlines is remarkably safe, as demonstrated by the long stretch between fatal crashes.

But deadly crashes have happened more recently elsewhere around the world, including one in South Korea that killed all 179 people aboard in December. There were also two fatal crashes involving Boeing's troubled 737 Max jetliner in 2018 and 2019. And last January, a door plug blew off a 737 Max while it was in flight, raising more questions about the plane.

Federal officials have been raising concerns about an overtaxed and understaffed air traffic control system for years, especially after a series of close calls between planes at U.S. airports. Among the reasons they have cited for staffing shortages are uncompetitive pay, long shifts, intensive training and mandatory retirements.

President Donald Trump added to those concerns when he blamed the midair collision over Washington D.C. on the "obsolete" air traffic control system that airports rely on and promised to replace it.

Even with all that, officials have tried to reassure travelers that flying is the safest mode of transportation. And statistics back that up.

The National Safety Council estimates that Americans have a 1-in-93 chance of dying in a motor vehicle crash, while deaths on airplanes are too rare to calculate the odds. Figures from the U.S. Department of Transportation tell a similar story.

What is being done?

The National Transportation Safety Board and Federal Aviation Administration are investigating these recent crashes and close calls to determine what caused them and look for ways to prevent recurrences.

There have already been troubling revelations about the midair collision, but it will take more than a year to get the full report on what happened.

The NTSB always recommends steps that could be taken to prevent crashes from happening again, but the agency has a long list of hundreds of previous recommendations that have been ignored by other government agencies and the industries it investigates.

Transportation Secretary Sean Duffy has said the public is right to say that crashes like the recent ones are unacceptable. That is why he plans to make sure "safety is paramount" as he leads the agency that regulates all modes of transportation.

"I feel really good about where we're at and where we're going and the plans we have in place to make sure we even make the system safer and more efficient than it is today," Duffy said in a Fox News interview.
