Narrative:

I was PIC and was aware of the expanded P-49 tfr to 30 mi radius and radio. After takeoff a frequency of 121.5 was monitored. Shortly, 2 F-16 military aircraft approached from the east and flew formation with my aircraft. I attempted communication on 121.5 with no success. I was then contacted by gray approach on 121.5. They advised contact on another frequency. Contact was made and they advised me to turn to a heading of 270 degrees. I immediately complied and advised our destination of horseshoe bay. A short time later, I was cleared direct to horseshoe bay. I was then directed to call them on landing and remain at the terminal for contact with secret service agents. The agents arrived and conducted a personal interview with me and my passenger. We were then released. Assessment: navigation around tfr (P-49), is difficult on the northwest quadrant due to lack of navaids and identifiable landmarks. A westerly wind contributed to making a ground track further to the east of our intended flight path. In addition, lack of timely communication on 121.5, until very close to the expanded tfr contributed to the alleged tfr incursion.

Title: PLT OF SMA MISJUDGED HIS POS RELATIVE TO THE EXPANDED P-49 PROHIBITED AREA AND WAS INTERCEPTED BY 2 F16 JETS WHEN HE ENTERED.

Narrative: I WAS PIC AND WAS AWARE OF THE EXPANDED P-49 TFR TO 30 MI RADIUS AND RADIO. AFTER TKOF A FREQ OF 121.5 WAS MONITORED. SHORTLY, 2 F-16 MIL ACFT APCHED FROM THE E AND FLEW FORMATION WITH MY ACFT. I ATTEMPTED COM ON 121.5 WITH NO SUCCESS. I WAS THEN CONTACTED BY GRAY APCH ON 121.5. THEY ADVISED CONTACT ON ANOTHER FREQ. CONTACT WAS MADE AND THEY ADVISED ME TO TURN TO A HDG OF 270 DEGS. I IMMEDIATELY COMPLIED AND ADVISED OUR DEST OF HORSESHOE BAY. A SHORT TIME LATER, I WAS CLRED DIRECT TO HORSESHOE BAY. I WAS THEN DIRECTED TO CALL THEM ON LNDG AND REMAIN AT THE TERMINAL FOR CONTACT WITH SECRET SVC AGENTS. THE AGENTS ARRIVED AND CONDUCTED A PERSONAL INTERVIEW WITH ME AND MY PAX. WE WERE THEN RELEASED. ASSESSMENT: NAV AROUND TFR (P-49), IS DIFFICULT ON THE NW QUADRANT DUE TO LACK OF NAVAIDS AND IDENTIFIABLE LANDMARKS. A WESTERLY WIND CONTRIBUTED TO MAKING A GND TRACK FURTHER TO THE E OF OUR INTENDED FLT PATH. IN ADDITION, LACK OF TIMELY COM ON 121.5, UNTIL VERY CLOSE TO THE EXPANDED TFR CONTRIBUTED TO THE ALLEGED TFR INCURSION.
