Here’s what to know Incidents have ranged from the midair collision that killed 67 people near Washington in January to an airliner clipping another in February while taxiing at the Seattle airport. Federal officials have tried to reassure travelers that flying is the safest mode of transportation, and statistics support that. But the cascade of headlines about things going wrong on airplanes is drawing increasing attention. Here is a look at some of the recent tragedies and mishaps: Recent fatal crashes — Two small planes collided in midair near an Arizona airport in mid-February, killing two people who were on one of the aircraft. Following the collision, one plane landed uneventfully but the other hit the ground near a runway and caught fire. The crash happened at Marana Regional Airport near Tucson. — A small commuter plane crashed in western Alaska in early February, killing all 10 people on board. The crash was one of the deadliest in the state in 25 years. Radar data indicated that the plane rapidly lost elevation and speed. The Coast Guard was unaware of any distress signals from the aircraft. — A medical transport plane that had just taken off plummeted into a Philadelphia neighborhood in late January, killing all six people on board and one person on the ground. The National Transportation Safety Board said its cockpit voice recorder likely hadn’t been functioning for years. The crew made no distress calls to air traffic control. — The collision between an American Airlines passenger jet and an Army helicopter above the nation’s capital killed everyone aboard both aircraft in late January. 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. — A jetliner operated by Jeju Air skidded off a runway, slammed into a concrete fence and burst into flames in late December in South Korea after its landing gear apparently failed to deploy. All but two of the 181 people aboard were killed in one of that country’s worst aviation disasters. Incidents with injuries — The American Airlines plane that caught fire at Denver International Airport on Thursday had been diverted there because the crew reported engine vibrations. While taxiing to the gate, an engine caught fire, prompting slides to be deployed so that passengers could evacuate quickly. The people taken to hospitals had minor injuries. — A single-engine plane carrying five people crashed and burst into flames on Sunday in the parking lot of a retirement community near a small airport near Lancaster, Pennsylvania. Everyone on board survived. Three people were taken to an area burn center. — A Delta Air Lines jet flipped over while landing at Toronto’s Pearson Airport in February. All 80 people on board survived, but some people received minor injuries. Witnesses and video from the scene showed the plane landing so hard that its right wing was sheared off. Investigators said that when trying to determine the cause, they would consider the weather conditions and the possibility of human error. Close calls — A FedEx cargo plane made an emergency landing at a busy New Jersey airport earlier this month after a bird strike caused an engine fire that could be seen in the morning sky. The plane landed at Newark Liberty International Airport. There were no reported injuries. — Pilots on a Southwest Airlines flight that was about to land at Chicago’s Midway Airport were forced to climb back into the sky to avoid another aircraft crossing the runway in late February. Video showed the plane approaching the runway before it abruptly pulled up as a business jet taxied onto the runway without authorization, federal officials said. — In early February, a Japan Airlines plane was taxiing on the tarmac of Seattle-Tacoma International Airport when it apparently clipped the tail of a parked Delta plane. There were no injuries reported. — In early January, passengers panicked when a man aboard a JetBlue plane that was taxiing for takeoff from Boston’s Logan International Airport opened an exit door over a wing, trigging an emergency slide to inflate. Other passengers quickly restrained the man and the plane didn’t take off. ...read more read less
