Army Lt. Col. Mike Humphreys said the first, a Cessna 152, entered the restricted area Saturday near the Palm City resort where the Obama was staying for the long weekend, CNN reported Monday.
Five hours after that plane was escorted out of the area by a F-16 fighter jet and a Coast Guard helicopter, F-16s intercepted a Lancair 320, the defense command said.
That plane left the restricted airspace after the fighter jets arrived, the defense command said.
The third plane, another Cessna aircraft, was intercepted near Palm City Sunday morning and landed at Okeechobee Airport, where it was also met by local officials, CNN said.
