Military aircraft were scrambled by the Department of Homeland Security to escort a plane to the ground at the Dade-Collier Training and Transition Airport.
The FAA said there was some kind of incident with a man trying to buy a Cessna 425 in Brooksville, Florida.
The FAA says the man took off in the plane for a test flight around 2:45 p.m. and never came back, which prompted DHS to get involved.
