Maintaining Perspective by Jef Allen First,
let me go on the record as stating that I am absolutely moved by the
profound sadness and loss which has befallen the families of the seven
astronauts killed in last weekend's tragic destruction of the space
shuttle Columbia. It was a terrible sight to witness, virtually in real
time, as the disintegrating pieces of the spacecraft arced through that
brilliant blue sky on our televisions, like so many glowing embers from
a child's sparkler on the Fourth of July. Stunned, we sat transfixed;
knowing that we were distant witnesses to the violent deaths of seven
human beings. The simultaneous beauty and horror of the spectacle were
incongruous. Yet,
as affected as I was by the unfolding events of that Saturday morning, I
could not help but juxtapose the shuttle’s demise with that of US
Airways Express flight 5481 that left Charlotte, NC bound for Greer, SC
with 21 souls on board January 8, 2003. On that Wednesday morning,
moments after takeoff, the commuter aircraft went into a steep nose-up
attitude, rolled over and crashed to the earth next to a maintenance
terminal. Upon impact, the plane exploded into a fireball, incinerating
every passenger and crewmember on board, burning them beyond recognition
in a flaming mass of white-hot aluminum and aviation fuel. The
US Airways passengers weren’t “heroes” in the media-hyped sense
that we understand today. They were simply normal
folks going about their daily lives. They were heading back to
school, or visiting friends, or earning a living and providing for their
families the best way they knew how. Among the dead were college
students, a retired
nurse, a
family from the Bahamas, and numerous businessmen, the people that
make our economy work, that crank the engine of enterprise on a daily
basis, all to no great fanfare. They left behind wives, kids, sisters,
brothers, parents, friends, fellow church members, employees, coworkers,
bills, mortgages, goals and aspirations--all the same exact things that
the ill-fated astronauts left behind. Yet
where is the national memorial for them? Where was the 24X7 news
coverage for days on end? Where was the president with his "moment
of silence"? Where was the national mourning, the outpouring of
angst and grief for these fellow citizens? Where were the talking heads
of cable news blathering on for seemingly endless hours, filling the air
with inanity and speculation regarding their tragic passing? Where were
the editorial
cartoons of their commuter plane passing through the Pearly Gates?
Other than those who had direct association with the victims, did anyone
in America miss a beat that January morning, except to note that another
commercial airliner had crashed? Why
is it that we took the news of their fiery demise in stride, with
nothing more than an "Oh, that's terrible!” forgotten by the time
the next J-Lo story broke on Entertainment Tonight, yet we are
collectively apoplectic over the astronauts' deaths when the shuttle
crew was arguably in a much more precarious position from the moment
they volunteered for the job? Sure,
there is the aura of “the unknown,” the excitement and glamour that
surrounds space travel. There is also the sense that these astronauts
were explorers, seeking out new worlds and performing complex
experiments for the betterment of mankind while living the adventure of
a lifetime. But, at the end of the day, isn’t the possibility of not
returning part of the risk package that explorers have accepted from the
beginning of time? Why should the shuttle astronauts be any different?
Why do we turn out in droves to place flowers at the Johnson Space
Flight Center, yet we drive right past Douglas International Airport in
Charlotte, NC with nary a second thought? Has the relative frequency
with which private and commercial aircraft crash inured us to the horror
of those occurrences? Were the final moments for those commuters any
less horrible than those of the shuttle crew? Whose death should we more
closely identify with, the death of a professional explorer, or the
death of a businessman preparing for his morning meetings? In the final
analysis, is there really any difference? I read in a news report the other day that NASA scientists had recently performed a statistical analysis of the probabilities associated with failure of the space shuttle system. It seems they found that one mission in every 75 was likely to have a catastrophic failure. In
May of 1998, the British science magazine New Scientist did a
study of the probability
that a rocket failure (either Soviet or American) would significantly
delay the construction of the International Space Station. The results
of their analysis were as follows: "The
probability of at least (emphasis added) one launch failure
resulting in the loss of its cargo -- through an explosion, placement in
the wrong orbit or another mishap -- is 99.5 percent," New
Scientist said. "In fact, NASA and the Russian Space Agency should together expect to lose five missions, with the Russian rockets being the most vulnerable." The
magazine added that there was still a 73.6 percent probability of losing
one of the 33 shuttle missions associated with the ISS. NASA, of course,
disputed the claims at the time. New
Scientist continued: “But,
even assuming NASA's figure of 99.6 percent for the shuttle's
reliability since the Challenger disaster, and a generous 93.2 percent
for the Russian rockets, taken from published sources, the chance of
losing one assembly mission is 62.3 percent. With the supply flights, it
becomes 98.7 percent.” Columbia
STS-107 was overall shuttle mission number 113. We have lost two
shuttles, and their crews, since 1981. Ahead of schedule, yes, but not
outside the math. As sad as this situation is, it is bound to happen
from time to time. Accidents have a way of doing that. Even without the
burden of a bloated and aging bureaucracy like NASA, space travel is an
inherently risky proposition. Private contractors, while simultaneously
pursuing alternative methods of accomplishing our objectives in space,
would certainly never guarantee 100% safety for astronauts under their
employ, any more than an airline can guarantee that there will never be
another plane crash. If we continue sending human beings into space, we
will eventually lose more spacecraft, and future astronauts will likely
die as a result. Grow up, America, and deal with it. As a society, we
view the periodic immolation of airline passengers as an acceptable
risk, yet we find the deaths of astronauts hurtling back to earth at
17,000 miles an hour shocking? Exactly how naïve are we? The
fact that these missions do contain a great deal of risk is a surprise
to no one inside the system, least of all the astronauts who know the
dangers going into the job. Given the stresses that this equipment goes
through, it is truly amazing that disasters don’t occur more
frequently. The shuttle Columbia was traveling at Mach 18.3 when it
broke up. That's over 18 times the speed of sound, almost 13,000 MPH. At
those speeds, with the surrounding atmosphere superheated by friction to
3,000 degrees Fahrenheit, you don't enjoy the luxury of having too many
things get outside of acceptable performance parameters before NASA
declares the inevitable "SFO contingency" (Space Flight
Operations) and the locals in Lest
I be misunderstood, this is not intended to disparage the crew of
STS-107, nor am I being disrespectful to their memories, or their
families. I am not denying their dedication, professionalism and the
courage that it takes to fly into space. I just think as human beings we
have our priorities a little screwed up. Let the families of the seven Related
