UPON ARRIVING AT HOME AT APPROX 1900 HOURS I OBSERVED TO THE EAST OF THE CITY OF DELEON TEXAS TOWARDS THE CITY OF DUBLIN TEXAS WHAT APPEARED TO BE A SINGLE RUNNING LIGHT OF AN AIRCRAFT, BUT UPON FURTHER OBSERVATION I OBSERVED TO MORE LIGHTS FLASHING IN UNISON IN A TRIANGLE PATTERN,THE OBJECT WAS BEING FOLLOWED BY TWO AIRCRAFT WHICH I PERCEIVED TO BE LARGE JET POWERED AIRCRAFT,I OBSERVED THE TRIANGLE CRAFT AND CAME TO THE CONCLUSION IT WAS MASSIVE IN SIZE COMPARED TO THE TWO AIRCRAFT THAT WERE FOLLOWING,THE TRIANGLE CRAFT MOVED FROM NORTH TO SOUTH AT A RAPID PACE, THE TWO "CHASE" AIRCRAFT THEN BROKE OFF AND HEADED WEST TOWARD ABILENE TEXAS,THE TRIANGLE CRAFT CONTINUED SOUTH AND AFTER APPROXIMATELY FIVE MINUTES ON THIS COURSE THE THREE CORNER RUNNING LIGHTS LITE UP RED,THE CLOSEST THING I CAN COMPARE THIS TO IS AFTERBURNERS OR FLAMES,THE OBJECT WAS SOON OUT OFF VIEW AND I COULD NO LONGER OBSERVE,AFTER THE CRAFT WAS OUT OF VIEW A THIRD JET POWERED AIRCRAFT APPROACHED FROM THE WEST FROM THE ABILENE TEXAS AREA AND WAS ON COURSE TO INTERCEPT THE LAST AREA I SAW THE TRIANGLE SHAPED CRAFT.DURING THE TIME I OBSERVED THE CRAFT THE HAIR ON MY NECK WAS STANDING UP AND I COULD HEAR THE NEIGHBORHOOD DOGS BARKING AND MAKING MORE OF A FUSS THAN USUAL.
