There is a TFR (Temporary Flight Restrictions) in effect over Boston until further notice, according to the FAA.
More details as they become available.
Earlier Tuesday morning, two airline passengers were removed from their flight from Boston to Chicago.
It happened aboard United Airlines flight 636.
The plane was scheduled to leave just after 5 a.m. Tuesday.
But, its crew requested travelers and their bags go through screening again.
The flight didn’t take-off until about three hours later.
