Narrative:

The owner of aircraft X; mr X; medical was expired. I was asked to go along to safely and legally be PIC. The owner planned the flight and I assumed checked with FSS for WX and tfr's. We contacted naples ground tower and then fort pierce departure advising them of our flight path and destination. No one advised us of a tfr for saint petersburg area. We then went low along the coast for sightseeing. On the outer fringe of the tfr we were intercepted by an F18; the F18 seemed to be having trouble maintaining flight at such a slow airspeed; approximately 120 mph. It slowly passed and got in front and slightly left at the same altitude of us before turning left. By getting in front of us before starting his turn his jet turbulence almost stalled us twice. At such a low altitude if stalled it would have been impossible to recover. We tried to contact F18 on 121.5 with no success. We were also receiving interference from an ELT (not ours). We were cleared in to clearwater airport by ATC; to drop off a friend and then cleared out of the tfr area. Suggestions: PIC should doublechk tfr's as they pop up quickly. ATC may want to advise aircraft or airspace of a tfr such as they do for skydiving. Intercepting aircraft should be careful of their jetwash and if starting their turn in front of intercepted aircraft; they may want to descend slightly lower before turning if close and out in front. An alternate radio frequency may want to be assigned in case of an ELT activation or other interference. Supplemental information from acn 688534: tried to communicate on 121.5; but there was an ELT going off on that frequency. Called tampa approach; received another frequency; 118.5 I think. F18 did not answer on that frequency either. We watched as he went by; wiggled his wings; and we did that also. We were in slow flight; at approximately 500-700 ft above the water with an airspeed of approximately 130 mph; and I am sure that made it more difficult for the F18 pilot to stay beside us. The second pass waked us worse than the first.

Title: BE95 PLT GETS INTERCEPTED AFTER UNAUTH TFR ENTRY.

Narrative: THE OWNER OF ACFT X; MR X; MEDICAL WAS EXPIRED. I WAS ASKED TO GO ALONG TO SAFELY AND LEGALLY BE PIC. THE OWNER PLANNED THE FLT AND I ASSUMED CHKED WITH FSS FOR WX AND TFR'S. WE CONTACTED NAPLES GND TWR AND THEN FORT PIERCE DEP ADVISING THEM OF OUR FLT PATH AND DEST. NO ONE ADVISED US OF A TFR FOR SAINT PETERSBURG AREA. WE THEN WENT LOW ALONG THE COAST FOR SIGHTSEEING. ON THE OUTER FRINGE OF THE TFR WE WERE INTERCEPTED BY AN F18; THE F18 SEEMED TO BE HAVING TROUBLE MAINTAINING FLT AT SUCH A SLOW AIRSPD; APPROX 120 MPH. IT SLOWLY PASSED AND GOT IN FRONT AND SLIGHTLY LEFT AT THE SAME ALT OF US BEFORE TURNING L. BY GETTING IN FRONT OF US BEFORE STARTING HIS TURN HIS JET TURB ALMOST STALLED US TWICE. AT SUCH A LOW ALT IF STALLED IT WOULD HAVE BEEN IMPOSSIBLE TO RECOVER. WE TRIED TO CONTACT F18 ON 121.5 WITH NO SUCCESS. WE WERE ALSO RECEIVING INTERFERENCE FROM AN ELT (NOT OURS). WE WERE CLRED IN TO CLEARWATER ARPT BY ATC; TO DROP OFF A FRIEND AND THEN CLRED OUT OF THE TFR AREA. SUGGESTIONS: PIC SHOULD DOUBLECHK TFR'S AS THEY POP UP QUICKLY. ATC MAY WANT TO ADVISE ACFT OR AIRSPACE OF A TFR SUCH AS THEY DO FOR SKYDIVING. INTERCEPTING ACFT SHOULD BE CAREFUL OF THEIR JETWASH AND IF STARTING THEIR TURN IN FRONT OF INTERCEPTED ACFT; THEY MAY WANT TO DSND SLIGHTLY LOWER BEFORE TURNING IF CLOSE AND OUT IN FRONT. AN ALTERNATE RADIO FREQ MAY WANT TO BE ASSIGNED IN CASE OF AN ELT ACTIVATION OR OTHER INTERFERENCE. SUPPLEMENTAL INFO FROM ACN 688534: TRIED TO COMMUNICATE ON 121.5; BUT THERE WAS AN ELT GOING OFF ON THAT FREQ. CALLED TAMPA APCH; RECEIVED ANOTHER FREQ; 118.5 I THINK. F18 DID NOT ANSWER ON THAT FREQ EITHER. WE WATCHED AS HE WENT BY; WIGGLED HIS WINGS; AND WE DID THAT ALSO. WE WERE IN SLOW FLT; AT APPROX 500-700 FT ABOVE THE WATER WITH AN AIRSPD OF APPROX 130 MPH; AND I AM SURE THAT MADE IT MORE DIFFICULT FOR THE F18 PLT TO STAY BESIDE US. THE SECOND PASS WAKED US WORSE THAN THE FIRST.
