Driving North on Hwy 270 between hwy 40 & Ladue Rd. Crazy electrical storm some small clouds moderate too heavy lighting. on phone w/friend looking @ lighting storm off too NW off too my left slighty but through front car window. Lightning struck bright then dark, next flash same exact spot object spotted w/3 lights appearing too be on bottom Orion belt configuration Red, Orange, Blue, Green sky went dark again.. Next large lighting flash illuminated large bright rectangular shaped object @ which point object w/3 lights flew into bright rectangular object too it's right my left was obsorbed as in vanished followed by large rectangular object Shooting in a straight line across the sky too it's left my right @ a very un normally high rate of speed across the sky & vanished into thin air..just like that !!! Upon reaching my subdivision/street @ the end of culdesac & exiting my car standing in the driveway windy for about 5 sec then complete stillness @ which time I heard a very low deep in tone horn that sounded off about 7 or 8 seconds then more quite about 7/8 seconds followed by 4 very distinct thuds like a base drum with sounds of trees breaking coming closer too me & about 5 too 7 second delay in between each thud. This is what I believe too be the 4th encounter I've experienced in so much as 19 years.Last 3 within past 3 years. I felt a bit frightened bewildered & confused by all of them.3 of them in Missouri 1 in California. I knew instantly all 4 times that it was nothing that could be explained away.. By anything other then what they were each time!!!!Other then the feelings I've explained my immediate reaction was too tell someone what I had witnessed & heard..The most recent sighting I've explained on Sept 1st was caught on a sky cam from the top of a local news stations building which I was later privy too after explaining too a friend what I had seen as he was kind enough too forward too me the footage from their website weeks later something triggered me too look up that night on news webpage again & miraculously that portion of the footage no longer is on their pageHowever others had too have seen it also as I found a mere but unmistakable scrap of that same image on another site. This prompted me too inquire about a locally held Mufon mtgwhich I attended for the first time last night & since have decided too speak with others & probably become a member of this organization.Thank You for hearing me that is all for now.Ps as far as how many witnesses it was on a local news broadcast as well so I don't know I'm guessing 1000's ? but since I'm required too give a head count of witnesses too this event & was alone when I seen this personally .. going too have too say 1?
