Fascination With Aircraft

I find airplanes fascinating. The mere fact that a vehicle weighing many tons can actually fly is quite amazing, even though I understand the science behind it. My office is near Centennial Airport, giving me the opportunity to watch at fairly close range, as private jets and small propeller-driven planes come and go.

I took the photo above on my way home from work today. I like the fact that you can clearly see the wings configured for landing, along with the landing gears locked down. Because airplanes are moving at a relatively slow speed when taking off and landing, the pilot alters the shape of the wings to provide more lift at these lower velocities.

On the leading edge of the wings are slats that move forward and down to create a greater curvature on the front of the wing. Flaps are on the rear of the wings, and extend backwards and down. Both flaps and slats are extended during takeoff and landing. Next time you fly in a jetliner, notice this during takeoff, and notice that once the plane is climbing, the flaps and slats are retracted. Of course, the landing gears are pulled up almost as soon as the aircraft leaves the runway in order to reduce the drag of air friction.

On the top of the wings are spoilers. These are panels that extend up from the top surface of the wing. The pilot can use spoilers to slow the plane down after landing, as well as using one or the other to roll the plane toward one direction or the other during flight.

Another control surface on the back of the wings are ailerons, used to help turn the plane during flight. The tail has elevators that move to orient the direction of the nose of the craft, as well as the rudder which helps to steer the plane.

In my younger, less informed days, I actually caused a plane I was on to get out of takeoff queue because of ailerons. This was shortly after Northwest Airlines Flight 255 bound for Phoenix crashed into a freeway overpass in Detroit a short distance from the runway. The crash was caused by the flight crew's failure to extend the slats and flaps, causing the plane to not have enough lift for takeoff. All on board were killed, except for a four-year-old little girl. The crash occurred the evening of August 16, 1987.

Anyway, I was on a Southwest Airlines plane in queue for takeoff from Houston's William P. Hobby Airport, and noticed what I thought was a flap sticking up off the wing. With the Detroit crash in my mind, I thought better to be a living fool than a dead person who kept his dignity. I rang the flight attendant bell, and asked was that "flap" supposed to be sticking up. She didn't know, but called to the flight deck. The captain pulled the plane to the side of the taxiway and came back to ask me if there was a problem. I told him, "I don't know, but I bet you can tell me. Is that a flap that is not down, like the one that caused the crash in Detroit?" He looked out the window and said, "Oh, that. No sir, those are called ailerons, and they are fine. But thanks for letting us know."

When he returned to the flight deck, he came on the PA and announced, "We just pulled over for a visual equipment check, and we will be taking off in just a few minutes." Nice job, Randy!

One new feature you see on many planes nowadays are winglets. These are the vertical extensions you see on the tips of the wings. Aircraft engineers have found that these wing extensions reduce the whirling vortices of air that spin off the wing tips during flight, thus reducing drag and increasing fuel economy. Many airlines use the winglets as billboards to advertise their web sites or airline name to the passengers inside the plane.

If you look at the large version of my picture above, you can also see a wire extending from the top of the tail to the fuselage. This is a communications aerial or antenna. Although the terms are commonly used interchangeably, aerials are usually flexible wire, while an antenna is a rigid device.

My airplane piloting experience is limited to balsa wood gliders as a kid, but that doesn't stop my enjoyment and admiration of airplanes.

Random Thoughts on a Tuesday

A few miscellaneous and totally random thoughts...

First item: Rocktober continues, with the amazing run by the Colorado Rockies baseball club. A month ago, this team was in fourth place in the National League. Since then, they have won 21 out of 22 games. They beat the Padres in a Wildcard Playoff, swept the Phillies in the NLDS, swept the Diamondbacks in the NLCS to win the league championship, and are now headed to the World Series. This has to be the most incredible run I have ever seen in sports. The national media talks about it being a team of no-names that nobody knows. Well, they are about to hear more from Helton, Torrealba, Holliday, Tulowitski, and the rest!

Second item: Once again, the cultural literacy between people of different generations struck home to me. At work, someone told one of the new twenty-something employees that someone called him "Eddie Haskell". His reply? "Who is Eddie Haskell?" Leave it to Beaver is such a part of the collective memory that it amazed me that here is a coworker who was totally clueless about this bit of information. Granted, he was born a couple of decades after the show left the air, but it IS on Nick at Nite, for goodness sakes. Even though I was not born until 1953, I know who the Andrews Sisters were, and that it was FDR who said, "The only thing we have to fear, is fear itself". I know of, and appreciate, the music of Benny Goodman. I know the story of John Dillinger and Al Capone. I know about how President Herbert Hoover was blamed for the Great Depression in the wake of the 1929 stock market collapse. I know how Neville Chamberlain tried to appease Adolph Hitler to achieve "peace in our time", and how Winston Churchhill rallied the Brits over the radio during the bombardment of London by Nazi bombs.

This isn't the first time this has happened either. I had coworkers ten years ago who had no idea who said, "Ich bin eine Berliner". By the way, you look lovely today, Mrs. Cleaver! Is that a new dress?

Third item: The weekend storm has put the white snowcaps on the peaks of the Colorado Front Range. From Mount Evans to Long's Peak, the original Colorado Rockies are looking good with their snowy tops looking down on the prairie. Maybe I'll get a chance to take a picture of them soon!

What Are You Gonna Pick? Hot Pockets!

You just have to feel that a burglar in Appleton, Wisconsin was just hungry. Police report that an unknown intruder walked into an unlocked apartment, leaving all valuables behind. What did he take? A chicken and broccoli Hot Pocket, along with:

• A half-dozen eggs
• A pizza
• One can of beef ravioli
• One can of peaches

Someone this hungry obviously needed food for themself and/or their family. My opinion: the police should write the report and let it be. The occupant of the apartment should learn a lesson about locking their door. Anyone hungry enough to eat a Hot Pocket has to be pretty desparate for food!

Hail!

Hail coming down on the driveway

It's late Saturday and the unusual weather continues. It got real noisy here all of a sudden, as hail started pounding the area, making me glad I got my car back home and safely in the garage before this came in. The picture above shows my driveway being pelted by the hailstones, as well as white streaks of them as they plummet to earth. You can also see little stones bouncing up, looking like small comets.

The hailstones are a bit larger than a large green pea. Still, the way they are pounding out there, this would not be good for any car that is caught in the storm.

As I write this, the hail continues to come in, wave after wave, separated by periods of just rain. All in all, a good evening to stay indoors tonight!

Little Deer

One of a trio of baby deer who live nearby - Click photo for large version

Last winter after our back to back blizzards, the deer who live around here were having a tough time of it. They were out looking for food and not finding all that much available. I haven't seen many around for several months. Then this afternoon, there were three of these little guys standing around near the end of the street. I am not a deer expert, but I think the reason these are darker than the ones I usually see, has something to do with the season.

The other two started to leave when they saw me, but this little one stood by long enough for me to snap his portrait before making his departure. I think these creatures live in the nearby woods and ravine, but come out to eat and explore. Today is overcast, cool, and rainy, so I guess they decided it was a good day to come out. They are rather cute, don't you think?

Six Days to Gutsy Gibbon

In 6 days, one of my favorite Linux distributions, Ubuntu Linux, releases its version 7.10, known as "Gutsy Gibbon". I have used Ubuntu for a couple of years, on and off, since it was in the Warty Warthog and Hoary Hedgehog releases. The team at Ubuntu has always done a good job of putting together a nice distro, and I am curious to see what is new in this latest release.

Ubuntu's stability and ease of use are demonstrated by the fact that Dell sells it pre-installed on some of its computers. I actually wish I had bought one of them, rather than this Gateway laptop I purchased at Best Buy last January. This machine comes with Microsoft's worst operating system since Windows Me, the ever bloated and slow Windows Vista. This operating system can take a powerful machine and give you a user experience akin to running Windows 95 on an underpowered 386SX from 15 years ago.

I bought this laptop (Gateway MT3705) with the idea of loading Linux onto it as my primary operating system, but it appears that Gateway has included components that only work well with Vista, at least for now. Notably there are problems getting the sound card and wireless 802.11g internal card to work with either Windows XP or Linux. (Actually, the wifi card doesn't even like Vista all that well). Some brave souls have used a release candidate of the ALSA Linux sound system, patched it, and have successfully gotten the sound to work. The wifi will likely require using NDISwrapper and a Windows driver to work in Linux. Then I have read instances of people having trouble with the CD/DVD drive with Linux. Yeah, the machine is basically a piece of junk. I have already had to replace the keyboard and power supply in the last 2 months.

I am getting close to getting up the courage to risk hosing the system by putting Linux on at least one partition, along with the necessary patches to get it running. This machine should run great if I can get it working. I still want to leave a Vista partition for those things I have to have that won't run on Linux, notably Sim City 4 and Adobe Photoshop.

I do have a desktop system running Linux (Fedora 7), but have no place to put it. Plus, I do like the portability of a laptop. I may actually buy a second hard drive for the laptop, swap it out, and install Linux on that. Then if it just won't work, I can put the Windows drive back in. Or maybe I'll just try an external USB drive for this project. Then if that works, I'll feel more confident in partitioning the internal drive for dual boot purposes.

So here are the distros I have decided to try out on this machine:

• Ubuntu
• Fedora
• Linux Mint
• PCLinuxOS

Its scary, but if I get it working, I should have a better performing machine running a stable, lean, and capable system software. I'll let you all know how it goes once I get into it.

My Interstate Highway Travels

In my perusing of various web sites put up by other highway aficionados, I have seen maps of Interstate Highways they have traveled. There is a very good version out there where you can build a data file that will generate a map for you, but for me, it seemed like too much work for what I would get. Still, I thought it would be nice to get a visual of the Interstates that I have traversed in my travels.

I found a map on the web that is a bit different than what you usually see. This one is not to scale, nor is it geographically precise, but it sets out to show the highways as either vertical, horizontal, or diagonal lines. This seemed to fit the bill.

So, I took this map, used Photoshop to draw semi-transparent overlays to denote my travels, and the result is below. Not too bad, if not as precise as other efforts I have seen. It shows that I need to do some more road trips to cover some territory I have never driven. My coverage is shown in red.

Sports Fan?

Well, maybe I will have to take back my earlier comment about not being a sports fan for at least one weekend. As I write this, I am watching the Red River Shootout on TV. This is the football game between the Texas Longhorns and the Oklahoma Sooners, played at the Cotton Bowl on the grounds of the State Fair of Texas in Dallas (any real Texan knows it is NOT the Texas State Fair). I am always torn in my loyalties in this game, as these are my two favorite college teams. I still am amazed that the CU Buffaloes beat OU last weekend in Boulder. In any case, the Cotton Bowl is the perfect place for the Texas/OU game, as it is almost exactly halfway between Austin and Norman.

Then tonight at Coors Field, the Colorado Rockies have the chance to sweep the Phillies to get to their first National League Championship Series, after winning the first two games in Philadelphia. They have to be the hottest team in baseball right now, and the late season run to the playoffs has to be some kind of record. Although it is a clear, beautiful day today, by game time it is expected that a cold front with rain will move through the Denver area, possibly impacting the game. I imagine it will have to get pretty bad to postpone this one.

Back Online!

Anymore, having broadband Internet service is about the most important utility next to electricity and gas. In fact, it is more important than a home phone, although you can even get that over your broadband. So I am back online, and happy that I am.

Earlier I mentioned about teaching my sons, "If it isn't yours, don't touch it without permission". Well, the Comcast guy shows up, and there is not only no signal at my modem, there is none at the entry point, nor at the main junction box. He has to call the lineman out, as the problem is in the network.

So about an hour later, the lineman shows up. He repeats the tests here, and goes down the street to the next junction box. What does he find? Some idiot has opened it up and stolen a main line splitter. Now why would anyone do this? These are not consumer-grade splitters, but are only used on the network itself. In any case, Comcast did get it fixed, so now I have to "give props" to the guys who came out.

More Thoughts on an MP3 Device

Well, the decision making about a portable music player continues. Ryan left a comment on the last post that recommended another player I will definitely have to check out. I also dropped by Circuit City at lunch to check out what they have.

They did have the 8GB version of the Zen, and some nice Sony Walkman MP3 players. One had a built in FM radio with a 1.8" color screen. The other had no FM, but a 2" screen. The one with FM was $129 and the larger screen with no FM was $149. Both had only 4GB of memory with no SD card. Nice, easy to use buttons and slim, but a big compromise on space. They also had some nice Sansa units, but again, small memory space. There is no perfect device that I have yet to find. What would be nice is a version of the iPod Touch with a ton of memory, selling for about $200. Not this year!

So, what do I do? Maybe I just sit tight for now. I went ahead and bought headphones with a plug to fit the micro-mini stereo jack on my Motorola Q Smartphone and a 2GB MiniSD card. While the portable Windows Media Player in the Q has some major interface and functionality limitations, it is a cheap choice for now. Perhaps I will wait and see what the new Zunes do, or maybe the player Ryan mentioned will fit the bill. But in the meantime, the Q does have nice sound quality, and I can listen to my favorite podcasts and a few tunes on it. I will have to see what it does to the battery life, although I don't think it will be a huge power drain.

On another note, my Comcrap high speed internet died last night, so hopefully the guy can fix it when he shows up tomorrow morning. I am not feeling the Comcastic love! To quote the turtle in their commercial, Mr. Slowski . . . "And / or DUH!"

iPod? Nah, Probably Not!

A couple of years ago, my wife bought me a fantastic MP3 player, the Creative Zen Touch. This nifty little device had a 40 GB hard drive which is room enough for a heck of a lot of music. I really loved this player, and had it loaded with about 3000 songs, numerous podcasts, and audio books. Earlier this year, it was stolen. It really pisses me off. Why do people have to steal instead of buying their own stuff? It's one of the major life lessons I tried to teach my boys as they were growing up...if it isn't yours, don't touch it without permission. Simple rule.

Well anyway, I am finally getting ready to replace it with a new portable music player. These devices have come a long way in a couple of years, as most come with color screens and can play video as well as audio files. Microsoft just announced the next generation of their Zune, and a few weeks back, Apple introduced the new iPods. Now I must say, I am tempted by the iPods, especially the new iPod Classic and its choice of 80 or 160 GB hard drives. That could hold tens of thousands of songs. Still, as tempting as it is, I probably will opt for another player. Here's why.

First, although I have no experience firsthand, I have read reports of the iPod being a bit slow, as well as not having the best audio playback, something pretty important in a music player don't you think? Secondly, Apple has lately been treating its best customers with less than stellar service. The company's recently introduced iPhone was introduced with much fanfare, then after about 3 weeks, the price dropped $200! Now although this is wrong, I almost think the buyers happily spent the money to be an early adopter of the latest toy. Products do have lifecycles, and generally drop in price, but that soon?

But the really bad thing is that Apple is pushing updates of firmware out to purposely ruin, or "brick", iPhones of customers who have used software to unlock the phones from AT&T, allowing then to use the devices on other carriers. These phones are not Apple's property, but were purchased for premium bucks by these customers. They should be able to do what they wish with them. I am leaning toward the idea that any company that would do that doesn't deserve my money for their iPod, regardless of how nice it is.

So, after some research, I found that Creative, the maker of my stolen Zen Touch, has a new, flash memory based, 16 GB Zen coming out in a couple of weeks. No, it doesn't have the storage of a hard drive model, but should be very durable without the moving parts of a HDD. Plus, it has some things the iPods lack, including a built in FM Radio and a slot for SD memory cards to increase the capacity. Reports of the similar 8 GB and 4 GB models already on the market, indicate the new Zens carry on Creative Labs' reputation of excellent music reproduction. Plus, the Zen can use more file types than the iPod, such as WMV files, and is not tied to Apple's iTunes. I won't buy from iTunes anyway since the files are locked with restrictive DRM (Digital Rights Management), disallowing many legitimate uses of the music you buy. I will go with Amazon.com's un-DRM encumbered MP3s if I want to buy music online. In addition, the Zen reportedly has a very good color screen for viewing album art, photos and video.

So it is looking more and more that I will sacrifice storage capacity for the yummy goodness that is the new Zen. Besides, 16 GB plus an SD card slot should take care of most of what I want to carry around anyway, and it's twice the capacity of the new iPod Nano's highest capacity device. Still, the only thing holding me back is that I liked having all that capacity on my Zen Touch. Once I decide and get a little experience with whatever I end up with, I'll do a review here. Stay tuned!

Baseball Playoffs

I may be unusual in that I am not a full-bore sports fanatic. I don't live and die by the fortunes of any sports team. I rarely have a lot of interest in any sport until it gets down to playoff time, and usually only when one of the few teams I actually halfway care about, is in the thick of it. Still there are a few teams that I do follow occasionally.

A couple of years ago, my favorite baseball team, the Houston Astros, finally made it to the World Series. Oh man, I was happy about that. I have followed them since the Colt .45 days, and for them to get to their first world series was exciting. And heartbreaking. Swept by the White Sox, the 'Stros couldn't buy a win.

The Astros have given me some great memories though. Players like Nolan Ryan, the recently retired Craig Biggio, Jeff Bagwell, Kevin Bass, J.R. Richard, Jose Cruz, Roger Clemens, and many others gave me lots of great games to watch, either in person or on television. When I moved away from Houston, Minute Maid Park (formerly Enron Field) had not been built, and I have never seen a game there. For me, the Astros memories took place at the Eight Wonder of the World, the Harris County Domed Stadium, known as The Astrodome. Who can forget the flashy scoreboard that went berserk everytime the Astros won or hit a home run?

And what about the best playoff game of all time, Game 6 of the 1986 National League Championship against the New York Mets. Both teams joined the league 25 years prior, so it was a fitting match up. The game went 16 innings before the Astros finally lost. This game held the record for the longest postseason game in Major League Baseball history until 2005, when the Astros beat the Atlanta Braves in 18 innings.

So now, we come to a phenomenal season ending winning streak by my next favorite team, the Colorado Rockies. The Rox won 13 out of their last 14 games to come out of nowhere and force the San Diego Padres into a one game play-in to see who got to be the wild card team in the National League. The game, played last night at Denver's Coors Field went back and forth, with the Padres scoring in the top of the 13th. This extra-innings game was decided when the Rockies scored three runs in the bottom of the inning to advance. The final run was Matt Holliday's chin in the dirt slide into home, sending the Rockies to Philadelphia to play the Phillies tomorrow. What a great game it was!

Go Rockies! Now hopefully the Astros can use the off season to get it together and return to the World Series in 2008!
