Airline safety is on the rise, but near accidents are still more common than you might think.

Runway Incidents: 23
Close Calls: While landing on a slippery runway at Midway in December 2005, a Southwest Airlines 737 shot off the end of a runway and into a surface street, where it smashed into a car, killing a six-year-old boy. A National Transportation Safety Board investigation ultimately blamed pilot error, abetted by a lack of the soft concrete Engineered Materials Arresting Systems (EMAS) that would have slowed the plane after leaving the tarmac.
The Fix: Following that accident, Midway decided to fund and construct EMAS at the end of its runways.
Around 10 p.m. on a clear summer evening in 2006, United Airlines Flight 1015 was rolling down the runway at Chicago O’Hare, picking up speed, when the pilots saw something heart-stopping: an Atlas Air 747 cargo plane moving directly into its path. Unable to abort takeoff, the United pilot made a split-second decision to turn sharply. The planes avoided impact by a mere 120 feet.
Close runway calls like this are more common than travelers realize—or most airports like to admit. Runway incidents at airports are, on average, a daily occurrence in the United States. They range from near collisions to vehicles or people wandering onto a runway without permission.
And some airports simply have a higher number of close calls, based on our analysis. We looked at the Federal Aviation Administration’s latest Runway Safety Report and more recent runway safety statistics supplied by the FAA to determine which of the 35 busiest commercial airports in the United States have had the most near misses and other runway incidents over the past five years (2006–2010).
Rankings were based on both the overall number of runway safety occurrences and their severity, especially “A” and “B” incidents in which an aircraft collision was narrowly avoided or there was significant potential for a collision. (See the full methodology.)
While everything from weather to wildlife can contribute to an incident on the tarmac, “Two-thirds of all runway incursions are caused by pilot deviation,” says Wes Timmons, FAA’s recently retired director of runway safety. In other words, pilots simply ignore instructions from air traffic control. For better or worse, most of these offenders aren’t commercial pilots; of those two-thirds, says Timmons, nearly 80 percent are caused by small private planes. “Places where you have a lot of [pilot] training activity or a large number of flight schools,” says Timmons, “tend to see a larger number of runway incidents.”
The overall number of runway incursions fluctuates from year to year; fortunately, the vast majority are minor incidents where there’s little or no possibility for runway collisions or casualties.
Airports and the FAA are always working to minimize runway incursions. “We’re making significant progress,” says FAA spokesperson Tammy Jones. In 2000, U.S. airports recorded 67 serious runway incursions that could have easily led to injuries or fatalities. According to Jones, the total dropped to 12 serious incidents by 2009, and just six last year. Over that same span, the number of serious incidents involving commercial aircraft plummeted from 34 a decade ago to only 3 in 2010.
Since launching a call to action on runway safety in 2007, the FAA has put a number of new programs and technologies into service in cooperation with airports, airlines, pilots, and other concerned parties. These include conducting pilot seminars and air traffic controller refresher courses, identifying “hot spots” at major airports where the risk of collision is higher, and implementing new technologies like Runway Status Lights and airport surface detection equipment.
In fact, incorporating new airport and runway safety features has “accelerated greatly” in recent years, says Steve Jangelis, chairman of the Airport and Ground Environment Committee for the Air Line Pilots Association (ALPA), which represents more than 53,000 pilots flying for 39 airlines in the U.S. and Canada.
Yet runway incidents still occur. Here are the airports that have seen a higher percentage of them.
We looked at the 35 busiest airports in America over the last five years (2006–2010) and used information from the FAA’s Runway Safety Report and individual runway safety data supplied by the FAA. We averaged the Runway Incident Rate-the total number of runway incidents divided by the total number of runway operations (takeoffs and landings)-over the five years covered in our survey period. We then looked at serious (Category “A” and “B”*) runway incidents in which there was a strong or good possibility of a crash or human casualties. We assigned values to these incidents: 1 for “A” and 0.5 for “B.” We added these Category A/B incident scores to the incident rate per year to achieve an overall score and ranking. We’ve listed the 20 airports with the highest scores.
* Category “A” is a serious incident in which a collision was narrowly avoided. Category “B” is an incident in which separation decreases and there is a significant potential for collision, which may result in a time-critical corrective/evasive response to avoid a collision.
