- Everybody knows what space vehicles look like on the
way up. The explosive steam-enshrouded liftoff becomes a fiery upward trail,
brighter than the sun. The rocket rises, dims and arches over, aiming to
throw itself beyond the horizon and into space.
- But even after decades of space operations, many people
remain in the dark about what space vehicles look like when they come back.
- Satellite orbits slowly decay into near-circular paths,
skimming the upper atmosphere. Moving at 8,000 meters per second [17,000
miles per hour], they begin to flame at an altitude of 110 kilometers [68
miles], falling to 80-100 kilometers after five to ten minutes.
- At that point, maximum heating and deceleration cause
them to break up into fragments, which continue their gradual descent for
another five or ten minutes. Surviving fragments slow to 3,000 meters per
second [6,700 miles per hour] at a height of about 50 kilometers [31 miles],
where the flames die out.
- At the cost of their own existence, these hunks of cast-off
space junk provide earthlings with thrilling fireworks. However, when the
dazzling fireballs unexpectedly pierce the darkness, surprise, confusion
and innocent misidentification often result.
- Who built the flying triangle? <http://www.space.com/area51/sep_sighting.htmlEarly
last September, U.S. observers were treated to two glaring examples of
this phenomenon. A pair of larger-than-usual pieces of space debris fell
back into the atmosphere, one crossing the California-Oregon border late
on September 1, and the other streaking from New Orleans to central Florida
early September 7. Both sparked widespread amazement and awe, as well as
disbelief in "official explanations" and a new crop of UFO reports.
- Just before 9:30 PM PDT [12:30 AM ET] on September 1,
viewers along the Pacific Coast and as far inland as Nevada and Utah were
treated to the fiery spectacle of a tight formation of multi-colored flaming
fireballs crossing the sky, leaving smoke in their wake.
- Some observers noticed an even more spectacular apparition.
Near Travis AFB, a 13-year-old boy identified only as "Ben" told
his local paper he had seen a large dark craft with running lights.
- "It's got to be either something the [Air Force]
base made or a spacecraft from a different world," he told the reporter.
"There were huge blue flames coming out of a triangular object."
- According to an account distributed by California ufologist
Frank Moreno, Ben described the object as "a huge black mass which
might have gone unnoticed if it were not for this trailing flame which
shone behind it." The boy estimated the eastward-moving object --
festooned with small white running lights -- was no more than 300 feet
[92 meters] off the ground.
- Observers barely had time to collect and examine these
California reports when a second apparition blazed over the Gulf of Mexico.
As on the West Coast a week earlier, many people saw a formation of fireballs,
but a few saw only a single object with blazing lights or "windows."
- One truck driver rolled down his window and was shocked
to see a huge "object" that he estimated was only 75 yards [68
meters] away. As he remembered the encounter, the UFO had a "blimp-like
shape" and was about 450 feet [138 meters] long, with large windows
that emanated a bluish light.
- Robert Russell, a maintenance employee at the First United
Methodist Church in Sarasota, Florida, told UFO investigators he pulled
off the highway to watch a similar object: "It was like light and
I could see the outline of the passenger windows, but I couldn't see any
wings. I thought it might be a blimp...."
- Rejecting the official story
- Public affairs experts at US Space Command in Colorado
Springs quickly explained that the fireballs were falling space junk. The
first object was a spent fourth stage of a Russian communications satellite
launched the previous February; the second was the discarded third stage
from a similar launch just the day before.
- But many witnesses and ufologists jeered in derision.
On his UFOSEEK web page, ufologist Ignatius Graffeo insisted that "a
spent rocket booster . . .would be fiery, burning up, falling fast, and
would not be displaying blinking red, green and amber colored lights in
a controlled slow moving flight."
- Frank Moreno, who had distributed "Ben's" sighting,
was equally certain. The reports "seem contrary to falling space debris"
he said, because they "indicate multiple lights, flying in controlled
formations, parallel to the ground on their own trajectories," certainly
not "what would be expected of falling space debris."
- A classic misunderstanding
- Sadly for alien seekers, these reports are actually "classic"
cases of sightings of falling satellites, according to the "bible"
of UFO investigators, The UFO Handbook (Doubleday, 1979).
- Written 20 years ago by Allan Hendry, then the ace investigator
for the Center for UFO Studies in Illinois, the book documented the kinds
of eyewitness reports that different mundane stimuli can provoke.
- According to the book, meteors and returning satellites
have led to reports of " 'downed planes', missiles, fireballs, comets,
'swept-wing jets', cigars, saucers, sparklers, and sometimes formations
of individual lights."
- In particular, Hendry noted that "re-entries of
orbiting material move in a flat trajectory" parallel to the Earth,
and can be visible for up to three minutes as they slowly cross the sky.
- Astronomer (and talented space artist) William Hartman
went one step farther in his 1968 perceptual analysis for the USAF's "Scientific
Study of Unidentified Flying Objects". Based on actual case files,
he described what a witness may mistakenly perceive when seeing a formation
of bright fireballs: "He may even imagine a dark elongated form connecting
them so that they become lights on a cigar-shaped object, or even windows
on a cigar-shaped object."
