> SPACE SHUTTLE REENTRY OBSERVATIONS
>
> In response to my request for observations of the February 1, 2003
> Columbia reentry, I have received numerous reports. The following is a
> compilation of all of the usable accounts received.
>
> These reports have been edited for brevity and clarity. Many
> observers may sound upbeat about the disaster, but this is the result
> of my taking their comments out of context. Also, the location listed
> under an observer's name is that from which they viewed the reentry and
> may or may not be where they reside. Finally, text within [ ] brackets
> was inserted by me.
>
> Although all of the observations are interesting, several are
> especially so because the observer reported seeing or capturing images
> or video of puffs coming off of the Shuttle, a momentary brightening
> of the vehicle, etc. The observers who mentioned such phenomena were:
>
> Doug Allison
> Mike B.
> Rick Baldidge
> B. Bennett
> Mark Bixby
> David
> Bill and Nance Gault
> Doug Jones
> Ian Kluft
> Jay Lawson
> Dick Matthews

> "...Viewing location was hot springs road on the east side of highway
> 395 and north of the airport. I chose a spot approximately 1/2 way
> between the airport cutoff and what I take to be a fishing camp on
> Hot Springs road. There was 1 porch light approx 1/4 mile away and a
> very large wide open section of the sky was visible. Conditions
> overhead were very clear with the stars shining brightly. There was a
> slight haze on the south & western horizons, which may have been thin
> high clouds. I was lying on my back, feet facing northwest and
> scanning the whole sky, binoculars at the ready.
>
> I first noticed the Shuttle at ~30 deg (rough estimate) above the
> horizon as a faint fuzzy reddish spot, almost stationary. Glancing at
> my watch it was 05:53. At first it looked like the planet Mars,
> appearing a rusty reddish/yellowish/brownish and almost stationary.
> It grew larger & brighter as it moved across the sky, NW to SE.
>
> What struck me most during the whole event was the color change.
>
> Within 10 seconds of spotting it began losing the rusty red color and
> became whiter and brighter with a faint shade of pink. Then the color
> transitioned to much brighter white with stronger pink color and it
> began to leave a contrail. The pink tones became much stronger,
> transitioning to bright red, just like a road flare, with some white
> light mixed in. At this point it was almost directly overhead and
> leaving a strong contrail, twice as wide as a standard commercial jet
> aircraft. Through out the portion of the arc from +/- 30 deg
> (approximate) of apex, it seemed to flicker slightly. Using 10X
> binoculars at the point most directly overhead, 2 objects were clearly
> visible. One, very bright (Shuttle) object and another smaller, but
> very distinct trailing slightly behind and glowing like an ember. When
> I pulled the binoculars down the 2nd object was not visible with the
> naked eye. I watched it for 2 to 3 minutes before disappeared below
> the southeast horizon.
>
> The event so visually intense that I expected to hear sound, but there
> was none. I was left in awe. I did not have a camera..."

> Mike B.
> Los Angeles, CA
>
> Caught it !!
>
> From Los Angeles (Westchester, on the north edge of LA Airport). Just
> from the front porch, between the street trees, at 5:54:40, appeared
> at due north, just over the rooftops, caught it.
>
> I'd almost given up, as 5:53 was the planned time, and I could see a
> bit of high fuzzy clouds.
>
> Bare eyed, I thought I may have seen some sparks fly off, either
> debris, or plasma.
>
> Were we seeing the SUNLIGHT reflecting, or the plasma glow?
>
> Movement was quite fast, and I eventually lost it in trees.
>
> Only a few stars were visible overhead, but it was brighter than the
> visible stars."

> Funny thing was, several of us who saw STS-107 Saturday morning didn't

> The closest description I can think of is that it looked almost like
