Philadelphia International Airport arrivals were slowed Thursday after wildfire smoke reduced visibility enough for the FAA to cut the rate of incoming flights.
Air traffic control audio captured an American Airlines Flight 2536 pilot reporting ash sticking to the windshield on approach — something both the pilot and controller said they had not encountered before.
The smoke blanketing the Philadelphia area was carried south from active wildfires in Canada, extending the fires' disruption from air quality into aviation operations.
