SPOKANE, Wash. -

Calls started coming in around 2 p.m. Friday, from people wondering about fighter jets flying over Spokane and Coeur d'Alene. So, where did they come from? Your guess is as good as ours.

Three F-18s flew over the region, flying low enough to cause some concern for people living in Coeur d'Alene. A front desk employee at the Coeur d'Alene Police Department said their office received a flurry of phone calls. Several calls and messages came into the kxly4 News desk as well.

Our first call was to Fairchild Air Force Base, who referred us to Naval Air Station Whidbey Island. A public affairs officer there said they had no jets in our area; all of their aircraft were on the ground Friday, due to high winds. Officers there suggested we call Mountain Home Air Force Base and the Idaho Air National Guard. Both told us the jets were not theirs.

Before 3:00 p.m., the aircraft landed at Spokane International Airport. The airport spokesman said it's not unusual for jets to land there. In this case, the airport spokesman said he doesn't know where they're from, only that they're expected to remain on the ground there until Saturday.
