This might be a bit late but wanted opinions on this.
The Shuttle Challenger breaks up more than 40 miles high over Texas and NASA has thousands of different videos of this happening just in the Texas area and in the Texas portion of the flight path. In fact they recover a lot of pieces of it in Texas, they figure out the camera azimuth/angle and deduce the shuttle's speed and what apparent parts were breaking off and where they broke off at...all from video footage. There is about a 300 page document on the net about their findings.
F16's chased it?
Now a UFO is reportedly seen over a town of 15,000 people in Texas and not one photo or video is shot? And what of the other towns in the flight path? And they say F16's were chasing the thing? The only reason F16's would be chasing it is if it was caught on radar. And if was caught on radar then every airport in the flight path would have seen the thing. F16's AFAIK are only operated on a consistent basis now by the Air National Guard and F16 radar can see out to about 80 to100 miles (at least in the de-classified docs). An F16's stall speed is around 140 to 160 knots depending on config. Yet reports of the UFO say it was moving very slow. These two reports conflict. If the object was moving very slow, as slow as some say, no F16 could have chased it b/c it would have been 6 feet under after it deep stalled. If it was moving very fast (another report) then the chance of actually seeing the F16's is next to nil at low level. We've all been to airshows when they do the 'fast' flyby. You have about 1 to 2 seconds to see the jet before its gone. So fast or slow the stories don't hold any water.
Radar didn't detect it...or did it?
They say it was a mile long and a half mile wide and yet no radar was ever bothered by it? C'mon. Every radar beam within 200 miles of that town would have reflected off the thing. If we agree F16's were chasing it...then they obviously detected it on radar which means hundreds of radar stations would have picked the thing up. Heck...weather radar would have been blocked by it and shown up as an empty section on the screen or as ground interference. Weather radar beams normally expand 1000 feet for every 10 miles of travel. This means that if the beam hit an object at 30 miles and returned, it would return as a big solid block. There is no more information to display between the beams at that point. This is why storms appear blockier the farther from the radar they are. Weather radar often pickes up aerial returns from birds and planes. One would think if this thing could have been picked up..it would have. This is Texas after all and they have tons of doppler radar sites operated by the NWS. The sightings don't appear too far from Waco which has several airports in the area operating doppler radar that can see well out to around 180 miles in one direction. Doesn't add up.
I find all this extremely hard to believe and swallow.
