Narrative:

While flying my hang glider out of the gutzmers twin oaks airport I heard an approaching jet sound; flying from north to south at approximately 3500 ft; [a] multi-passenger jet; looked like a cessna citation. I was close enough to see the pilots in the cockpit. I was concerned about wake turbulence but encountered none. Other than that incident flight uneventful. Incident was witnessed by another glider in the vicinity.
