I’m not a UFO fan, but this is an interesting report. The MUFON report (warning, it’s a large pdf file) is also interesting. It’s worth reading at least the initial summary.
Inconclusive, as usual. But it looks as if several sorties of jet fighters, were sent out to have a look at it. And there are several military and/or LEO witnesses.
"Much more important than the possible sudden acceleration shown by the object is its trajectory heading. This object was traveling to the southeast on a direct course towards the Crawford Ranch, also known as President Bush’s western White House. The last time the object was seen on radar at 8:00pm, it was continuing on a direct path to Crawford Ranch and was only 10 miles away"
