Narrative:

I departed ZZZ airport at approximately XA45 on 1/wed/02, on a VFR pleasure flight. At all times I was squawking 1200 and monitoring frequency 121.5. At approximately XB30, I was intercepted by an F15. The F15 made a close flyby and then departed. No visual signals were observed nor were there any transmission received on 121.5. My position at the time of intercept was approximately 4 to 5 miles east of ZZZ airport at an altitude of approximately 10000 ft MSL. I immediately turned for the ZZZ airport and landed. Center contacted me upon arrival at the ramp and inquired about my flight. I found out at that time that I had missed the NOTAM that required a discrete VFR code to be squawked for all VFR operations within 50 miles of ZZZ VOR. I had not obtained a briefing from FSS personnel prior to the flight. I was aware of the restr within 3 NM of ZZZ and 3000 AGL. In reviewing this incident, I feel that the major contributing factor is the large number and size of the current NOTAMS that have to be reviewed. Obviously it is easy to miss one especially if you choose not to utilize the services of a FSS briefer.

Title: BEECH 33 PLT FLEW IN SPECIAL RESTR AIRSPACE WITHOUT SQUAWKING A DISCRETE VFR CODE.

Narrative: I DEPARTED ZZZ ARPT AT APPROX XA45 ON 1/WED/02, ON A VFR PLEASURE FLT. AT ALL TIMES I WAS SQUAWKING 1200 AND MONITORING FREQ 121.5. AT APPROX XB30, I WAS INTERCEPTED BY AN F15. THE F15 MADE A CLOSE FLYBY AND THEN DEPARTED. NO VISUAL SIGNALS WERE OBSERVED NOR WERE THERE ANY XMISSION RECEIVED ON 121.5. MY POSITION AT THE TIME OF INTERCEPT WAS APPROX 4 TO 5 MILES E OF ZZZ ARPT AT AN ALTITUDE OF APPROX 10000 FT MSL. I IMMEDIATELY TURNED FOR THE ZZZ ARPT AND LANDED. CTR CONTACTED ME UPON ARRIVAL AT THE RAMP AND INQUIRED ABOUT MY FLT. I FOUND OUT AT THAT TIME THAT I HAD MISSED THE NOTAM THAT REQUIRED A DISCRETE VFR CODE TO BE SQUAWKED FOR ALL VFR OPS WITHIN 50 MILES OF ZZZ VOR. I HAD NOT OBTAINED A BRIEFING FROM FSS PERSONNEL PRIOR TO THE FLT. I WAS AWARE OF THE RESTR WITHIN 3 NM OF ZZZ AND 3000 AGL. IN REVIEWING THIS INCIDENT, I FEEL THAT THE MAJOR CONTRIBUTING FACTOR IS THE LARGE NUMBER AND SIZE OF THE CURRENT NOTAMS THAT HAVE TO BE REVIEWED. OBVIOUSLY IT IS EASY TO MISS ONE ESPECIALLY IF YOU CHOOSE NOT TO UTILIZE THE SERVICES OF A FSS BRIEFER.
