Thursday's incident at LaGuardia airport that saw a jet skid off the runway is a reminder that air safety is an everyday challenge.
In 2014, the Federal Aviation Administration identified 1,264 runway "incursions." This year is on pace to beat that number.
The FAA defines incursions as "any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle or person on the protected area of a surface designated for the landing and take-off of aircraft." They could be as simple as a plane taking the wrong turn and going on the wrong runway.
Through the first five months of fiscal year 2015, the FAA has identified 513 runway incursions, compared with 469 last year.
At that pace, the total would be 1,383 for 2015, or 45 percent higher than in 2011.
