There are a lot of strange things about the Denver International Airport (hereafter, DIA), but the article linked by the OP does a fine job of
presenting a lot of misinformation, and presenting a lot of fairly normal information as though it was earth-shatteringly strange.
Let's start with the fact that the article contradicts itself.
From the fifth paragraph:
DIA was built with 50,000 of fiber-optics, 10,000 miles of copper, and was over budget more than 3 times the original amount.
From the "Some more interesting facts" section, bullet point 2:
The airport has a fiber optic communications core made of 5,300 miles of cable. That's longer than the Nile River. That's from New York City to
Buenos Aires, Argentina. The airport also has 11,365 miles of copper cable communications network.
Which is the correct amount of cable? It's bad enough when multiple sources aren't consistent, but when an author can't even agree with himself, it
seems a bit suspect.
There are also places where the article flat-out disagrees with reality.
From the text below the third photograph:
The airport was built in 1995 on 34,000 acres (53 square miles; 137.593 Sq.km) in spite of the fact that Denver already had what everyone said was
a perfectly fine airport - Stapleton - which was ordered closed when DIA was built so there "wouldn't be any competition".
That would be the "perfectly good airport" that suffered from inadequate runway separation? The one that faced a lawsuit from a nearby community
because of noise? The one that couldn't expand, and faced a legal battle over a desired runway extension? Sounds like a great place, doesn't it?
Stapleton was a very convenient airport, but that was about its only virtue by the time it was closed.
And, once more from the "Some more interesting facts" section. Final bullet point
The entire roof of DIA is made of 15 acres of Teflon-coated, woven fiber glass. The same material is on the inside as a layer, also. The place
looks like a bizarre (but kind of cool) scene out of "Dune", comprised of huge, spiked tent-like structures. The material reflects 90% of the
sunlight and doesn't conduct heat. So you can't see into the place with radar or see heat signatures.
The fiberglass roof won't show up very well on radar...that much is true, and it's the reason that the weather shields over most radar antennas that
have them are made of fiberglass. The metal supports holding up the roof, however, and the polished granite floor underneath that roof will show up
perfectly well, as will the very conventional vertical walls. I don't know where the part about 'can't see heat signatures' came from...I've
worked with IR cameras and film, and fiberglass doesn't do anything to stop thermal images unless there's a lot of insulation behind it...in which
case, it's the insulation, not the fiberglass.
Moving on to the "Things that are normal, but are presented as strange" department:
The several miles of optical / copper cable may sound like a huge number, but for a large commercial complex, the presented numbers don't seem that
high...single aircraft can have several hundred miles in a single airframe.
Same section, bullet point three:
The fueling system can pump 1,000 gallons of jet fuel per minute through a 28-mile network of pipes. There are six fuel hold tanks that each hold
2.73 million gallons of jet fuel. This is somewhere in the "no one will ever ever need this much" range.
Sounds like a lot of jet fuel...and it is, until you divide it by the 50,000 gallons that a Boeing 747 can take on. It's about 500 full refuels for a
747. 50-100 commercial flights a day (probably a low estimate), plus the demands of feeder / commuter flights and civil aviation could easily go
through that supply in less than a week. It might be amusing to look up total fuel bunker capacity for Dallas-Fort Worth or O'Hare, or Sky Harbor for
There are also a lot of 'conspiracy proofs' that the article explains on its own...you can't say that huge overruns in cost are covering up some
secret, then spend half your article discussing contractor fraud, and massive redesigns during construction.
As I noted at the top, there are, indeed strange things here...plenty of them. So many, in fact, that we don't need to create more out of
sensationalism and / or whole cloth.
