Air Force Reserve flying units in PA are at Pittsburgh(C-130H) and Willow Grove NAS/JRB (C-130E). (northern part of metro Philly). Air Guard units are at Willow Grove(A-10s), Harrisburg (EC-130), and Pittsburgh (KC-135). Nothing at Philadelphia. Pretty sure Navy Reserve doesn't have any flying units there either. Navy and Marine Reserves also have flying units at Willow Grove, which is about 25 miles from the Philadelphia airport.
Still 25 miles might be too close, better withdraw to Harrisburg, or maybe to one of the BRACed bases in the Dakotas. :)
Pull back to Ohio and Ontario then. Just get out of there ~ it’s too dangerous for Americans.
