For the second time in a week a tragedy was just barely avoided at John F. Kennedy International Airport, CBS2 HD reports.

Federal Aviation Administration officials say two airborne planes came within 600 feet of colliding on Friday.

The FAA moved quickly to change takeoff and landing procedures at JFK on perpendicular runways – the kind of runways involved in both incidents.

FAA spokeswoman Laura Brown says the Delta Flight 123, a Boeing 757, was landing on one runway Friday when the pilot decided to abort his landing and execute a go-around — a routine procedure often used during heavy congestion. That caused the Delta flight to intersect with the flight path of Comair Flight 1520, a regional jet that was taking off on another runway.

The incident came less than a week after Cayman Airways and Lan-Chile jets came within a few hundred feet of each other at JFK on Saturday night. In that incident, one flight was taking off, and the other was landing. However, the FAA downplayed the incident and the NTSB was said to have launched an investigation.

The Cayman Airways Flight 792 pulled up at the last minute instead of landing — around 8:30 p.m. Saturday and just missed Chile Flight 533 which denied the report.
