A plane taxiing for departure clipped another aircraft at Chicago O’Hare International Airport on Sunday evening, the Federal Aviation Administration said Monday.

No injuries were reported, both planes were of Boeing design, and the FAA says it will investigate the incident.

The left wing tip of Flight 11 from All Nippon Airways, a Japanese airline, struck the rear of Delta Air Lines Flight 2122 on Sunday around 6:30 p.m. Central Time, FAA spokesperson Tony Molinaro said. The All Nippon Airways flight was a Boeing 777, and the Delta Airlines aircraft was a Boeing 717.

The Chicago Department of Aviation did not immediately respond to a request for comment.
