Also, police in Newton, just west of Boston and the Logan Airport, are looking into a report from a driver that a man pointed a green laser at him and other drivers on Tuesday night, about two hours before the planes were allegedly targeted.
One plane had left Boston and was heading to Atlanta; the other was en route to Boston and flying over Providence, R.I.
The FAA pinpointed the coordinates to Forte Park in Newton, and police responded but did not find anyone.
Police do not know if the incidents are related.
The FAA and Newton police did not immediately return calls Wednesday for more details.
