Sputnik Rumors Revisited - Confirmed and Unconfirmed

Last night PBS aired NOVA: Sputnik Declassified shedding even more light on a topic that I’d blogged about earlier. For those of you who didn’t catch the show:

In 1955, President Eisenhower wanted information about Soviet ballistic missiles and formed a secret commission headed by Dr. James Killian (then head of M.I.T) to analyze the situation and provide recommendations. Recommendation number 10 of the commission’s report was to develop spy satellites (NOVA only shows that particular recommendation, I wonder what the other 9 were? Or, if there were more than 10?). But that recommendation triggered a question that no one on the commission or in the administration could answer: How would the Soviet Union react to a fly over by a U.S. satellite? What was the legal status of space?

To establish a legal precedent for the neutrality of space and the legality of spy satellites, Ike and his advisors decide to take advantage of the International Geophysical Year (1957 – 1958) and launch a civilian scientific satellite. The request for proposals go to two groups: a team at the U.S. Naval Research Lab (NRL) with a rocket called Vanguard and a team comprised of engineers under Wernher von Braun at the Army Ballistic Missile Agency and engineers at the Jet Propulsion Lab (JPL). Their rocket is called Jupiter-C.

In a controversial decision, the Eisenhower administration picks the NRL team over the von Braun-JPL team. NOVA points out that the Navy’s team (1) had the better satellite, (2) would use a brand new rocket not associated with a military weapon (more in keeping with the goal of establishing the neutrality of space), and (3) that there was resentment within the Pentagon against von Braun and his history with the Nazis. Considering that Eisenhower was the Supreme Allied commander in WWII and had led the effort to defeat the Nazis, I personally think that this had a lot to do with it.

But von Braun and his team are undeterred and decide to keep working in secret. Apparently rumors do start to circulate that von Braun is disregarding his direct order not to launch a satellite and a year later, 1956, the Army orders an audit during a key test of the Jupiter-C rocket. At this point one of the engineers being interviewed admits that during the audit he hid the satellite in the trunk of his car. NOVA doesn’t say so explicitly but it seems plausible that the auditors were on hand to make sure that von Braun and his team did not “accidentally” launch a satellite into orbit during the test. In the end, the Jupiter-C goes up with a dummy satellite that does not have the second and third stage engines necessary for orbit. The flight is flawless.

After the test, von Braun and his team keep another rocket stored in a warehouse, ready to go. On inventory records they list it as part of an experiment to see if rockets could be stored for long periods and still work.

I was waiting at this point for a mention of the court martial of Col. Nickerson (detailed in my previous post) as an outcome of the audit. But NOVA provided no information.

Now, time to fast forward. The Soviet Union launches Sputnik in October 1957. Two months later, on nationwide live TV, the Navy’s Vanguard rocket rises majestically a few feet off its pad, sinks slowly backward, and then explodes in spectacular fashion (See it here).























Von Braun and his team get the call and he says he’ll have it all done by the end of January 1958. He does.

So, for those of you keeping score:

CONFIRMED
1) The U.S. could have orbited a satellite before the Soviet Union.
2) Von Braun was working in secret to launch a satellite.
3) Word leaked out about von Braun’s work and this triggered additional oversight from the U.S. Army.

PLAUSIBLE BUT STILL UNCONFIRMED
1) Col. Nickerson was court martialed because of von Braun’s secret satellite plan.

The Promise of PAVs and the Reality of our Disappearing Airports

To accelerate innovation in general aviation the way the Ansari X-Prize led to a flurry of aerospace start up companies, NASA has set aside $2 million dollars for a Personal Air Vehicle (PAV) competition called the PAV Challenge.

The competition intends to promote a new class of general aviation airplanes that are easy and inexpensive to fly and maintain, STOL capable so that they can take off and land at small, short field airports located close to our homes and final destinations, and quiet enough so that the people living next to these airports don’t mind them at all.

The first competition was held this past August and officiated by the Comparative Average Fuel Economy (CAFÉ) foundation. The total prize money was a somewhat unexciting $250,000 and, with the exception of David and Dianne Anders’s ultra quiet RV-4, so were the airplanes (a Cessna 172 won Best Handling). The overall winner was a carbon fiber, 2 place airplane called a Pipistrel Virus which has got to be the worst airplane name ever (“Oh no, he’s infected with the Pipistrel Virus. Run!”). Supposedly it's pronounced “Veerus”.

Still, mighty oaks from little acorns grow and there’s enough money left for at least 7 more competitions.

All I've got to say is they better hurry up.

While it is true that the U.S. has more airports than any other country - 5,400 public use airports (nearly four times more than second-place Brazil) according to the Aircraft Owners and Pilots Association (AOPA) - it is also true that airports are disappearing from urban and suburban areas at an alarming rate, sometimes overnight (I’m looking at you Chicago).

How fast? According to General Aviation News (www.generalaviationnews.com) the U.S. had almost 7,000 public use airports in 1973. They've been disappearing at a rate of almost one a week for over thirty years.

Need some more convincing, just go over to the U.S. Airport Finder on Airport-Data.com (here). In the two drop down fields on the right select ‘Airport’ for ‘Facility Type’ and ‘All’ for ‘Facility Use’, scroll down to the bottom, and enter the city and state of your favorite metropolitan area.

You should notice that inside the loop of most cities there are few if any airports. Of course, Airport Finder will only show the airports that are still there and not the airports that were there and are now sitting underneath someone’s condo. If you really want to depress yourself and have a good cry don’t rent The Iron Giant, go check out the Abandoned and Little Known Airfields website. It chronicles the destruction of general aviation airports across the United States. One of them is Houston Gulf (A.K.A. Spaceland) where my dad learned to fly. It went underneath the bulldozers in 2003.

One bright spot though, if you go back to the Airport Finder and select ‘Heliport’ for ‘Facility Type’, you see that most metropolitan areas still have quite a few heliports.

It looks to me like for PAVs to succeed they're going to have to be VTOL capable, not just STOL.
