Two United Airlines aircraft have clipped wings on the tarmac at Chicago O'Hare International airport.

The wingtips of the aircraft, an Airbus A320 operating flight UA645 to Portland, Oregon, and a parked Boeing 737-700, clipped at concourse C at O'Hare on 15 August, United confirms.

No passengers or crew were injured in the incident, the Chicago-based carrier says.

The A320 (MSN 0842) was delivered new to United in 1998, and the 737 (MSN 28939) was delivered new to Continental Airlines in 1999, Flight Fleets Analyzer shows.

Continental and United merged in 2010.
