When NASA launched shuttles into orbit, the folks at Mission Control weren't be the only ones following its every move.  Jeff Challender watched every second of shuttle footage available on cable television from his Sacramento home. And he recorded it, adding it to his collection of hundreds of missions, for proof.  Proof of what, he didn't know. But Challender believed the National Aeronautics and Space Administration cameras were catching glances of UFOs.  Alien spacecraft, space animals, secret government experiments or none of the above -- Challender had no idea what they were. But despite debunkers who said he was staring at ice particles or other space junk, Challender did not think the white spots occasionally traveling across his screen could be explained by normal means.  These flying objects were, at least for him, "Unidentified."  "I don't go for the flying saucers and little green men routine," he said. "All I know is that there is something appearing on NASA video that doesn't belong there."   

Though there were many UFO trackers in Sacramento, he was one of only a handful in the world that scoped NASA flights for clues. And for his patience and dedication to detail, watching video that he said produced about 10 seconds of "interesting" material out of several hundred hours, he
become respected as a self-taught "expert" in the wider UFO community.  "He had probably more expertise than anyone else, certainly outside of government, in looking at the film," says George Filer, a retired Air Force major who runs a UFO Web site from New Jersey.  Challender, disabled by a severe spinal injury, laid on a mattress surrounded by an arsenal of recording equipment for his work: nine VCRs, stacks of VHS tapes, two DVD burners and a DVD player. With his massive, hand-built, quadruple-hard-drive computer in front, he seemed suspended in some kind of space vessel himself.  But the only thing that hinted of extraterrestrial interests was a little silver alien, perched on top of his computer.  Challender grabed the NASA footage from Channel 72, run by the Sacramento Educational Cable Consortium. From this mission he probably examine 30 to 40 hours of tape, sometimes straight from breakfast to when his family called him to dinner.  The longtime aviation junkie started taping missions in 1997, just for fun, to edit each one into a documentary. But in 1999, he saw something that grabbed his attention: an illuminated dot, pulsating as it whizzed across the screen. Then, later, he saw many white dots moving around, changing direction and speed.  What were they? Challender then began tracking similar "anomalies".  "I want answers," said the former railroad laborer. "I believe something's going on and the facts are being kept from us."   

NASA isn't so sure.  "I'm not aware of any visuals of [extraterrestrial)  activity," says Fred Brown, then executive producer of NASA Television.  Challender pointed to incidents where the camera seemed to zoom in on one of the dots and then cuts off the live footage -- signs, he said, of a cover-up.
Nonsense, Brown says. "If those things were out there and we were trying to hide them, we wouldn't put them on NASA Television."  Challender is probably seeing bits of liquid or ice, close to the camera, blown around by jets of gas from the shuttle, says Seth Shostak, an astronomer at the SETI Institute, a nonprofit organization running what used to be NASA's "Search for Extraterrestrial Intelligence."  "You have to be careful," he says. "They're very impressive if you're naive."  But Jack Kasher, a retired University of Nebraska, Omaha, physicist, says he's viewed Challender's findings, concluding that they aren't ice particles and challenging anyone who says so
to prove it.  Still, Shostak says, why would SETI spend millions searching for alien radio signals if there were Martians buzzing around every NASA mission?  Shostak believes that there is alien life.  If 10 percent of stars had planets and 1 percent of  those supported life, there could be millions of worlds with life just in our galaxy, he calculates. 

NASA would have no incentive to hide any evidence. That would be the greatest thing for NASA. Their  budget would go up instead of going down," he says.  Bernard Haisch, ex-director of the California Institute  for Physics and Astrophysics, has led several NASA  studies, and doesn't think the civilian agency is  involved in any coverup -- but he thinks there probably  is one.  In fact, there are quite a few government people and  aviation experts -- even famed astronauts Gordon Cooper  and Edgar Mitchell -- who believe the government knows  more than it's telling. 

"I know there's something out there because I've chased 'em," Filer says. Flying in the Air Force in 1962, he  was ordered to follow a supernaturally large  object detected by radar and came close enough to see  its lights before it disappeared.  Aviators apparently have so many such
experiences that  one ex-NASA scientist founded the National Aviation  Reporting Center on Anomalous Phenomena, which compiles  UFO reports from pilots.  Since the government no longer investigates UFO  reports, the task falls on these private organizations  and on amateurs.   

The Mutual UFO Network, for example, is dedicated to  investigating all sightings. Cynthia Siegel, director  of the Sacramento chapter, is training half a dozen  locals to become "field investigators," to document  sightings with interviews, photographs and video --  even soil samples.  "There are
so many more accounts than people realize,"  Siegel says.  The National UFO Reporting Center recorded two  Sacramento-area reports in December: a "cigar-shaped  craft" and a "triangular craft with three large white  lights."    Challender, searching for more using a different  technique, founded Project P.R.O.V.E. It stands for  "People Recording Orbiting Vehicles from Earth,"
which  says it all. Challender holds his ordinary camcorder to  the sky when the International Space Station passes  over Sacramento and waits for something unusual. So far  ... nothing.  "But I don't give up hope," he says.    An even more difficult project may be establishing  credibility for UFO buffs. To help change the kooky  image, Linda Willitts of Folsom works on Project
Disclosure, which gathers testimony from top government  and military figures who "believe."  On the other hand, she participates in what some  consider the definition of kooky, traveling around the  country to summon ETs through meditation.  "We ask them to show up and they always do,"
she says.    That's not Challender's style. He shirks the "true  believer" label and diligently fills out incident  reports for everything he sees, striving to be  scientific.  Yet, he knows he's unlikely to solve the puzzle from  his home in Sacramento.  "The only way I will find out is with full government disclosure. Or if something lands in my front yard and asks me if I want a ride," he
says with a chuckle. "But I'm not holding out for that."
