The US Federal Aviation Administration is investigating two separate incidents in which commercial aircraft suffered blown tyres while landing at Chicago O'Hare International Airport within hours of each other on Monday. The incidents form part of a recent run of tyre-related problems affecting passenger aircraft at American airports, prompting scrutiny of maintenance and runway conditions even though both planes landed without serious injury.

Details of the specific airlines and flight numbers involved were not fully confirmed in initial reports, though the wider context includes a separate case in which a Delta flight bound for New York's JFK Airport triggered a large emergency response after an in-flight alert about possible flat tyres, involving around 141 New York Fire Department personnel, though it landed safely. The FAA has not yet released findings on the cause of the O'Hare incidents.
