PALM CITY, Fla. (AP) — Federal Aviation Administration officials say they're investigating three more apparent breaches of the no-fly zone above President Barack Obama's vacation spot along Florida's Atlantic coastline.

According to the FAA, a Lancair 320 allegedly entered the temporarily restricted airspace Saturday afternoon. The plane was flying from Boca Raton to DeLand.

On Sunday morning, FAA officials say a Cessna allegedly entered the restricted flight area. The plane landed at Okeechobee Airport.

A Robinson R44 helicopter allegedly entered the restricted zone Sunday afternoon. The FAA says the helicopter landed at Okeechobee Airport.

Two F-16 military jets escorted a small plane away from the no-fly zone over Palm City on Saturday morning. U.S. Army Lt. Col. Mike Humphreys said the planes forced the Cessna 152 to land in Witham Field in Stuart.
