Incident Overview
On an unspecified date, U.S. Air Flight 373 and American Airlines Flight 695 were both taking off from Chicago O'Hare International Airport. The two aircraft converged at the intersection of Runway 32R and Runway 4L. During this event, they came within approximately 20 feet of each other. Both flights had been cleared for takeoff by the local controller at O'Hare Tower.
Controller Actions
The local controller was simultaneously providing additional severe weather avoidance (SWAP) clearances. In the process, he inadvertently forgot that he had already cleared U.S. Air Flight 373 for takeoff. About 20 seconds later, he cleared American Airlines Flight 695 for takeoff. The clearance of the second flight occurred while the first aircraft was still on the runway, leading to the close proximity between the two aircraft.
Proximity and Runway Configuration
Runway 32R and Runway 4L intersect at O'Hare International Airport. Both aircraft were engaged in takeoff roll when U.S. Air Flight 373 passed over American Airlines Flight 695 at the intersection. The vertical separation between the aircraft was reported as 20 feet. No collision occurred, and the event concluded without further incident.
