A pair of loud, low-flying Wisconsin Air National Guard F-16 fighter jets kept the phones ringing at Sturgeon Bay's Cherryland Airport Tuesday afternoon.  The jets were part of a routine military training exercise called Operation: Noble Eagle. The F-16s with the 115th Fighter Wing out of Madison had to intercept a pair of Civil Air Patrol planes from units outside of Door County, including one from Appleton.  Cherryland Airport Manager Keith Kasbohm says, based on phone calls he received, people were caught unaware of the exercise and so was he.

Kasbohm says the Door County Sheriff's Office was also kept busy taking calls from people about the low flying aircraft.
