Apparently a Chicago to San Juan flight had to turn around and head back to O'Hare this morning. Approximately 9:30AM Central Time. Listening live to the landing on the combined tower. American 395. Starting a thread. Reported a need to check brakes on landing, but not sure what caused the emergency to return to KORD in the first place.
Updated - they landed on 28R...putting here so I can remember later.
