Bright light like an atomic exploation . it sucked the power out of tbe lights at tbe air port i was setting at, sucked power out of tbere lights, there beacon light was so low on power it took 15 min or so to fully power back up. the light was right in front of me, just like a fladhbulb, no sound at all, no streak of light, it was dusk an tbe smy was clear. i was in a car an pop.... this light went off across the aitport runray in a field. the brightest light i ever sern, it cover all my line of site looking west. like it either came from tbe ground up or so fast i never seen anything coming down but i was not looking totaly forward as i was looking to my left out the frivers side window, i was looking out the driver window at shadows that tbe airport hanger lights were making on the car an i had my hands out the window making shadow.Hand figures to pass the time as my two buddys went inside tbe air port to call his dad, we had a flat an drove a mime to tbe airport to call his dad to bring a spair tire. tbey were inside tbe airport on tbe phone but i stayed in tbe car. the light was so big, bright an fast. like a flasbulb going off in your face, no sound of anytype an i had the windowns down as it was summer an hot in texas. after tbe fladh of light, i noticed tbe airport hanger side light was super dem an i first tbought it went off, tben i looked up at tbe big beacon light an it was moving real slow an tbe light inside was super dem also... it took over 15 min for tbe lights to co.E back full power, tbey came up slow over 10-15 or so min... my friends come back, i adk did yall see that light? they ssid no. his dad showed up right after an i asked his dad an his mom did they see a big bright light on tbere way out an both said no. the airport is on the outside of town. so i go back into town get my car an ask all my friends if anyone seen a bright light in tbe sky, everyone said no, seen notthing. so tbe extt day i went to see my mother an father an my brother who lives in bangs tx a small town west of brownwood about 12 miles from away. he was tbere so i went in, tbey were sitting round the table having a cup of coffee, my brother was sayiing last night while setting outside there house in bangs that he an our cousion who also lived in tbe house next door were talking an they both saw a bight bright light back toward brownwood, they tbought a air plane might crashed as it was in tbe airport area, the called tbe pice an reported a big light or explosion but did not hear a sound. i tbey told my family i seen that light but i was almost ground zero... they saw it 12 or more miles away an looked like a explosion but to me it lite tbe whole sky infront of me up, big flash.... this was in 1976, in brownwood texas thank you
