I WAS BORN IN 1951,SO I WAS 16 YEARS OLD AT THE TIME OF THE SIGHTING. I LIVED AND STILL LIVE ABOUT 5 MILES EAST OF LAKE THONOTOSASSA.I WAS STANDING OUT IN THE FRONT YARD AT OR ABOUT 9:OO P.M. WHEN I NOTICED A LARGE BLUE GREEN LIGHT,(MORE BLUE THAN GREEN) IN THE NORTH WESTERN SKY.WHAT MADE ME TAKE A CLOSER LOOK WAS THAT THE LIGHT WAS MOVING AT A VERY FAST RATE OF SPEED,IT TOOK PERHAPS 20-30 SECONDS TO MOVE FROM THE NORTHWESTERN HORIZON TO THE NORTHEASTERN HORIZON,AT WHICH TIME I LOST SIGHT OF THE LIGHT. MAC DILL A.F.B. IS ABOUT 25 MILES TO THE SOUTHWEST OF MY POSITION AND I SAW JET AIR CRAFT ON ALMOST A DAILY BASIS.THE F4 WAS THEN FLYING IN THE AREA SO I KNOW ABOUT HOW LONG IT TAKES TO MOVE ACROSS THE SKY. THE LIGHT I SAW WAS BIG ENOUGH THAT HAD IT BEEN THE LIGHT OF AN AIRCRAFT (JET) IT WOULD HAVE TO HAVE BEEN CLOSE ENOUGH THAT I WOULD HAVE BEEN ABLE TO HEAR THE ENGINES. I WENT INSIDE AND TOLD MY DAD WHAT I'D SEEN.HE ADVISED ME TO CALL THE SHERIFF'S DEPT.I DID SO AND WAS TOLD TO CALL MAC DILL A.F.B.WHEN I CALLED MAC DILL I EXPLAINED WHAT I'D SEEN.THE MAN I SPOKE WITH ASKED ME WHERE I LIVED.I TOLD HIM,HE THANKED ME AND HUNG UP. ABOUT 15-20 MINUTES LATER 3 AIR FORCE JETS FLEW DIRECTLY OVER MY HOUSE TRAVELING FROM THE SOUTHWEST TO THE NORTHEAST WHERE THE LIGHT HAD DISAPPEARED. I DON'T KNOW WHAT IT WAS I SAW,BUT I FELT THEN AND STILL FEEL THAT THE LIGHT WHATEVER IT WAS WAS UNUSUAL.I WASN'T ON DRUGS OR ANYTHING LIKE THAT.I'VE OFTEN WONDERED WHAT IT WAS I SAW. I KNOW THE INCIDENT DOSEN'T SOUND LIKE MUCH.BUT AFTER THINKING IT OVER FOR SOME TIME I DECIDED TO TRY AND REPORT IT. THANKYOU FOR YOUR TIME AND CONSIDERATION ((name deleted))
