Chicago: A Chicago-bound plane was forced to make an emergency landing early Tuesday after crew members reported a "possible smoke threat," the Federal Aviation Administration said.
The incident occurred around 6:40 a.m. Tuesday on GoJet Flight 4423. The CRJ 700 was headed to Chicago's O'Hare International Airport but was forced to turn back to St. Louis Lambert International Airport instead.
Details of what may have caused the smoke were not immediately clear. The FAA said it was investigating the incident. United Airlines, which owns GoJet, did not respond to a request for comment.
