Half a dozen people got sick while on-board a flight from Germany to Chicago.
Emergency crews and six ambulances met Lufthansa Flight 432 from Frankfort when it touched down at O’Hare just after 11 p.m. Saturday.
Paramedics took two of the six people complaining of illness to the hospital.
The flight was already hours late after making an emergency landing in London because of a passenger who may have suffered a heart attack.
No word on the condition of the remaining sick passengers.
