'Southwest, Stop!' Air Planes Avoid Runway Collision By Less Than 400 Feet in Washington D.C.

Two airliners almost collided on a runway at Reagan National Airport just outside of Washington, D.C. on Thursday morning. A Southwest Airlines Boeing 737 was cleared to taxi across a runway, while a JetBlue Embraer ERJ-190 was about to take off on the same runway. WTOP reports the potential disaster was averted as the planes were within 400 feet of each other. While no one was hurt and no aircraft was damaged, the Federal Aviation Administration is investigating the incident.
