Just seen on Fox news:

The pilot of a Piper Cherokee was reportedly forced to land at a
Philadelphia area reliever airport after "flying right over" the
International Airport. The news reader also said that the pilot FLEW
NEAR A NUCLEAR POWER PLANT (emphasis from the news reader, not me).

Video showed the plane on the runway or taxiway surrounded by police
cars. The pilot was seen exiting the plane and assuming the prone
position on the ground.
