		<description>I&#039;m sure that &quot;most&quot; ufo&#039;s can be explained as natural phenomena or optical illusions.  However, some, for example, when multiple airline pilots (on different airlines) verify a strange object, which is also captured on radar -deserve closer attention and ...honesty! 

 I am frankly disappointed in the gross display of prejudicial, unscientific thinking and willingness to accept unproven hypothoses &amp; erroneous conclusions; after all, its Bad Astronomy.  Not to mention, the name-calling is disappointing as well.

I would think that subscribers to &quot;Discover Magazine&quot; would be more willing to ...discover, and explore intruiging and mysterious new data.  To simply dismiss data, or a hypothesis, just because there happen to be &quot;nutjobs&quot; who believe in ufos, is not at all logical.  There are also pulitzer prize winning doctors, professors, scientists, astronauts, etc. who also attest to the existence of extra-terrestrial spacecraft, or ufos.

But to get back to the topic, there are a lot of really compelling videos from NASA (some of it live-feed) that show truly bizarre anomalies.  As with &quot;ufos&quot; many of these anomalies aren&#039;t actually anomalies, rather, they represent particle reflections, satellites, debris, etc.  But many obviously do not fit these explanations.  Now, I&#039;m no astro-physicist, but I know that &quot;they&#039;re just ice crystals&quot; doesn&#039;t cut the mustard for many of the anomalies photographed by NASA.

For instance, the video in question (I believe) is that taken from the Discovery shuttle in 91, which shows a light colored object (or &quot;ice crystal reflection&quot;) seeming to appear in Earth&#039;s atmosphere, travel slowly, slow down and stop right before a flash, and then take off in another direction (seeming to leave the atmosphere &amp; jet out into space).  My questions are as follows.  
1) How is it physically possible for an ice crystal to change velocity (slowing down and stopping)  and direction due to the impact of thrusters or jets.  
2) Just after the object stops, there is a flash, and then a beam of some sort that shoots out from the Earth directly toward where the object was prior to jetting away.  What is this &quot;beam&quot; that seems to have been aimed in the direction of this object.
3) Since the camera is focused on infinity, as it is apparantly focused on the far away Earth, how would an object of any moderate size very near the shuttle show up, as such, on camera?  We can see that when the camera pans down to the shuttle bay, everything is blurry until the camera focuses on close-range.  

If anyone can offer me an explanation that is logical and physically possible, I would gladly accept it.  Sure, its not as fun as government Star Wars equipment shooting at giant ufos, but I&#039;m all about finding the TRUTH (whether its unbelievably strange OR undeniably boring).  I discuss this NASA video, (as well as the multitude of astronauts who claim to have seen alien spacecraft) on my humorous blog, What&#039;s Up With Aliens.  Feel free to comment &quot;politely&quot; on any of my posts, at whatsupwithaliens.blogspot.com

This has been a truly invigorating discussion!! Let&#039;s keep our eyes and our minds open.</description>

		<description>IF NASA IS NOT TAMPERING WITH PICTURES AND EVIDENCE SUCH AS IN GOOGLE MARS, AND MOON, AND IF THERE EXISTS NO UFO, WHY ALL THE &#039;&#039;NERVOUSNESS&#039;&#039;?  PEOPLE ARE SERIOUSLY STARTING TO MAKE CONNECTIONS LIKE WHEN THERE&#039;S A SUPPOSED UFO AND THEN THEY HAVE SOMETHING ON TV TO PROVE IT WAS FAKE, AND ALL THESE ATTEMPTS LOOK VERY EXTREMELY DESPERATE, THEY&#039;RE BASICALLY GIVING THEMSELVES IN.  THERE&#039;S A HUGE COVER UP BECOMING MORE AND MORE OBVIOUS TO PEOPLE AND WORD OF MOUTH IS GETTING AROUND VERY RAPIDLY!  IT&#039;S VERY OBVIOUS THAT ALL THIS IS FOR SELFISH REASONS, AND THAT MOST PEOPLE TYPING HERE HAVE EITHER BEEN PAID OR WORK FOR THE GOVERNMENT TO STICK UP FOR THEM.  IN THE END THE TRUTH WILL SHINE AND OUR BROTHERS FROM THE STARS WILL COME, SADLY THE GOVERNMENT HAS SOLD THEMSELVES TO THE GREYS.</description>

		<description>I think that someone needs to experience a UFO within a hundred feet and have knowledge of what is within the realm of what G forces a person could survive.  I never believed in UFOs and always thought there was some natural or earthly explanation for the sightings people have witnessed.  One evening, my son called me outside my home, excitedly telling me to look up our driveway.  An oval shaped disk  a hundred yards across, “I know this because it was at the top of our trees”, moving at a walking pace out to the middle of a field.  This craft proceeded to move skyward to the point that it looked like a million other stars in the sky.  It happened within a second. I served many years in the Air Force training pilots and know that the G forces that this craft would of sustained would of killed anyone. You tell me. I still believe that most sightings out there are explainable, but I now know that there is something out there that is unexplained and not of our making.</description>

Clearly, quite a lot of the people on here know what they&#039;re talking about - those were pretty good descriptions I read of the behaviour of gasses in a vacuum. And, just so you know, there are those of us with a pretty good attention span. I read all 226 posts, because I found it, y&#039;know...interesting. Then again, it&#039;s easy to criticise those who are clearly quite clever - they&#039;re just so downright threatening, aren&#039;t they?

How do you know they&#039;re leprechauns, and not mostly-invisible pink unicorns? Where&#039;s your evidence? ;)

		<description>Arguing with people who believe that UFOs are alien spacecraft is like arguing with creationists...it can&#039;t be done.  You can&#039;t debate someone who bases their viewpoint on philosophical belief from a position of logic.  I, for one, believe that the &quot;ice crystals&quot; are ACTUALLY leprechauns--they just got tired of sharing their gold with us humans and went to hide out in space.  That&#039;s why they seem to scatter every which way when they see the space shuttle coming.  They don&#039;t want the astronauts getting their gold! ;)  Ice in space...geeze...</description>
