The Unfriendly Skies

Living in a rural area, and especially the past week spent at a remote camp, I get to appreciate the quiet of the sky. No, or precious few planes to annoy me with their sound and vision. At night, and without the light-pollution of urban areas, nothing but bright stars.

NASA and Boeing would like to change all of that. From Red Nova News:


It's a frustrated commuter's escapist fantasy: literally lifting your car out of a clogged highway and soaring through the skies, landing just in time to motor into your driveway.

Researchers stress that the ultimate dream - an affordable, easy-to-use vehicle that could allow regular people to fly 200 miles to a meeting and also drive 15 miles to the mall - is still probably decades away.

But engineers at NASA, Boeing Co. (BA) and elsewhere say the basis for a flying car is there. People have been building, or trying to build, such vehicles for decades.

The problem is, those ideas have generally required both a lot of money and the skills of a trained pilot. And melding cars and planes hasn't always been very successful.

"When you try to combine them you get the worst of both worlds: a very heavy, slow, expensive vehicle that's hard to use," said Mark Moore, who heads the personal air vehicle division of the vehicle systems program at NASA's Langley Research Center in Hampton, Va.

The goal isn't just to create a neat gizmo: These vehicles will become more appealing - and necessary - as highways and airport hubs grow more clogged, and commutes more distant.


These vehicles will never be necessary if our country takes the proper steps to build mass-transit to the point where THAT'S appealing. Furthermore, such Jetson Cars would only increase the US dependence on oil since I imagine such vehicles will use quite a lot. Is that really what we want?

I really don't look forward to the day (and fortunately I probably won't be around for it) when rich folks clog the skies with their Jetson Cars day and night. And as the cars become more popular, what happens to any hopes of enjoying the night time quiet, maybe amateur astronomy, or the daytime vistas of mountains, lakes, expanses... What happens to those quiet moments of hunting or fishing when we start having these flying SUVs screaming all about as the wealthy now find it easy to get to their vacation homes? And lastly, how much harder will it be to keep our borders secure if anyone can just "hop" over?

And when these Jetson Cars crash, who pays for the burning wreckage that falls on our homes and property? Who will enforce "traffic laws" up there? Aren't urban skies noisy and crowded enough now?

Maybe I'm just an old fuddy-duddy but this is the kind of progress I can do without.

Guess again, Jeff. Mass transit is only cost-effective when you have a.. umm, ehhh, [what's that word I'm looking for? OK, here it is--] mass of people all wanting to go from the same Point A to same point B at the same time.

I empathize with your desire for peace and quiet, but stunting development of advanced aircraft is not the answer. It has exactly the opposite effect: it keeps old air-cooled piston engine technology in the skies.

As far as "jetson cars", as you call them, are concerned, they would be advanced enough that they wouldn't require the piloting skills today's general aviation aircraft require. Technologies ranging from WAAS to the FAA's Capstone to NASA's "free flight" AGATE program are geared toward making flying more useful.

These aircraft would be far quieter. And for what it's worth, a general aviation airport is demonstrably quieter than a typical city street.

This is not to be confused with a major air carrier airport, where jets depart every minute all day long. Those do create congestion and noise.

Most GA airports have only a few operations per day, and the ones on approach are silent. The departures generate some noise, but except in specific cases (Bonanzas, C185s, and other planes with the prop turning < 2700 rpm), the dB exposures are quite low, even right on the field.

If you support general aviation, you're supporting the development of Q-tip propellers, high compression engines (the prop turns slower), hush kits, and other things that make the environment quieter.

Regarding our dependence on oil, a properly designed modern aircraft is going to be more fuel efficient than any SUV. Diamond Aircraft just developed a new twin engine turbo diesel, the DA-42, that uses 2.7 gallons of fuel per hour per engine. 5.2 gallons to go 160 nautical miles (184 statute miles), which translates to 35.4 mpg. Show me an SUV -- better yet, show me ANY ground based vehicle -- that can go 184 miles per hour while getting 35.4 mpg.

General aviation is vital to the country's economy and security. See http://www.gaservingamerica.com/
