Does anyone know......?
At this time of night, with this runway alignment, does KBOS use different tower frequencies?
Communication box on airport diagram implies separate freq\'s....
Also, initial part of takeoff roll off both runways involved....the other aircraft would not be visable - blocked by terminal complex and/or (referred to in article) aircraft parked on taxiways.
