I have a Nikon D5000 camera. I also have a 2006-vintage cell phone with a  built in camera. Oddly, the cell phone camera doesn’t get much use. Still, on the recent B-17 flight I took some cell phone photos, just to send them to someone while flying around (and, yes, the cell phone worked while in flight).

The cell phone camera is a cheap piece of crap compared to the Nikon, or even a simple point-n-click. As a result, the images are both small in size, and low in quality. But they provide an interesting view of the propellers. Due to the “rolling shutter” effect, the propeller moves a fair amount during the exposure. But rather than being simply blurred, it gets… mutated.

Interestingly, while the digital photos taken with the Nikon do not exhibit these motion artifacts, a brief bit of video taken with the same camera does exhibit this in spades.

A bit less than a year and a half ago, I stumbled across the B-17 Aluminum Overcast purely by chance: I was in Logan, Utah, and saw a B-17 fly over. As anyone would, I drove to the nearest airport, and there it was. I took some photos, and that was about it.

Last Saturday, a visitor pointed out a newspaper article mentioning that Aluminum Overcast was in West Jordan, Utah, and was available to take paying passengers up for a flight the next day. A decision was made (in about a tenth of a second) that we’d reserve a few seats.

On Sunday morning we arrived bright and early… about an hour early. Better early than late, anyway.  We were the first ones there, and were alone for a good long while… a bit disconcerting. The B-17 requires a certain number of passengers, or otherwise it doesn’t fly. Not surprising, of course… a four engine bomber pushing 70 years in age is an expensive thing to operate. Fortunately, by the time things started to happen, it was clear that the flight would be full up.

The B-17 is a small plane. While it might’ve been Big And Bad in the early days of WWII, these days it’s really quite dainty. Aluminum Overcast carries 10 passengers, plus three crewmen (pilot, copilot, engineer), and a surprisingly small load of bombs… presumably fake ones.

Looking forward from the entry hatch, showing the at compartment where six passengers would sit.

Looking aft from the entry hatch, showing the closed-off entry to the tailgunner position. Sadly, not available for sitting-in.

The first passenger to board the plane gets to sit in the flight compartment, at the engineers station. The next three, including myself, sit in the radio operators compartment. There is a largish window directly overhead… back in the day, the radio operator was sometimes  given a single machine gun with which to help swat Messerschmitts out of his sky, but on my flight the window was removed. This left a sizable hole in the roof.

View up through the overhead hatch.

Looking forward from the radio operators hatch. This would be approximately the last time I’d be able to get this angle.

Once everyone was on board and seated, the engines fired up one at a time.  The engines sound just like they do in the movies… except they sound real. While I’ve always liked the sound of the Merlin engine in the Mustang best, the sound of a B-17 engine from within the fuselage is not to be sneezed at.

The B-17 is not exactly the cleanest burning of beasts. As soon as the first engine fired up (outboard engine on the right wing), blue oily smoke filled the air. Neat. Authentic !

Looking aft from the radio operators position right after engine ignition, showing the smoke-filled fuselage.

Following that came the cliched taxiing out to the runway followed by the takeoff run. If you’re familiar with jetliner takeoffs… this ain’t it. Instead of a “whoosh” sound coupled with a smooth acceleration shoving you back into your seat, the B-17’s engines rumble to a clanking roar, and the B-17 just sorta throws itself down the runway. Compared to jet transport, it’s about as smooth as throwing a coffeecan full of bolts down a flight of stairs.

The passengers of course had to stay seated and belted in until after the plane was in the air, after which we could get up and wander around. While it was certainly LOUD, the open hatch overhead was not the screaming maelstrom of nightmarish winds I might’ve thought. In fact, there was no real wind at all so long as you stayed inside the contours of the aircraft; and even a few inches outside, the environment was pretty smooth. But it went from “no wind” to “oh, crap, the wind just ripped my camera out of my hands, bashed it against the rudder and showered shattered bits of camera and control surface over Utah Lake” within a distance of no more than two inches. As a result, I could get good shots aft, okay shots to the side, and no shots forward. To do forward shots, I would’ve needed to stick the camera well above the upper surface… and with a wind speed of maybe 140 miles per hour, the drag on a good sized camera amounts to a “metric shit-ton,” and I was simply unable to hold the camera in  position to get a forward shot. Oh, well.

One of the neat bits was the ability to go forward to the glazed nose. To get there you have to pass through the bomb bay, crossing a narrow catwalk. At the forward end of the bomb bay is a narrow V-shaped passageway.

Manifestly NOT “fat-guy friendly.”

Forward of the bomb bay is the cockpit. A nice place to visit, but you wouldn’t want to pester these fellers while they’re on the job.

If you duck down below the cockpit, you can get into the bombardiers position. Given the small size of the B-17, the nose is surprisingly spacious.

The glazed nose was liberally bugsplattered, making forward photography problematic. Can’t blame the B-17 or its crew for that… try driving a car around here sometime. Clouds of bugs spring up out of nowhere, especially near the lakes. Oh well…

The total flight time was half an hour, with about 20 minutes for wandering around. With ten passengers, this meant only a few minutes per passenger up in the nose.

After an entirely too short a length of time in the air, the plane came back down to the runway, taxied back to its spot and the passengers left the plane. Oddly, I was the last one off… sticking around a bit to take a few more photos.

On the whole, the impression the plane gives is that of “power.” As there is absolutely no effort given to mute the engines or insulate the airframe, every last bit of noise or vibration comes through loud and clear. And while that would be damned annoying in a means of transportation, it’s nothing but pure awesomeness in a ride like this.

A nearly forgotten mid-1970s test vehicle built and flown at NASA-Dryden. NASA description:

The Oblique Wing Research Aircraft was a small, remotely piloted, research craft designed and flight tested to look at the aerodynamic characteristics of an oblique wing and the control laws necessary to achieve acceptable handling qualities. NASA Dryden Flight Research Center and the NASA Ames Research Center conducted research with this aircraft in the mid-1970s to investigate the feasibility of flying an oblique wing aircraft. The oblique wing rotates about a pivot to allow the wing to be set at its most efficient angle for the speed it is flying. At higher speeds the wing takes advantage of the gains achieved by a swept wing while offsetting some of the drag producing disturbances. The oblique wing concept could result in transonic drag reduction and have the added benefit of producing corresponding fuel savings.

The aircraft’s wing was capable of being skewed up to 45 degrees left wing forward. The aircraft was flown in two configurations, the short and long tail version. To aid in the remote piloting task, a television camera was mounted in the nose of the vehicle to provide forward looking views. Power was provided by a 90-horsepower, four cylinder, air-cooled, reciprocating engine.

The flight program was limited to three flights flown over Rosamond dry lakebed at Edwards Air Force Base, of approximately 1 hour each. After the first flight, longitudinal stability problems required a configuration change. The tail was moved back three feet and this configuration was used for the last two flights. Maneuvers were performed at wing skew angles of 0 to 45 degrees. This program provided information which led to flight testing a piloted aircraft with an oblique wing, called the AD-1.

Hmmmph. Just noticed that *some* of the posts had had commenting mysteriously shut down. Haven’t seen any comments in a little while… not overly surprising since blogging  has faded away lately (except for on one of my other blogs, which averages one view per day… yer all missin’ out!), but if the commenting dropoff is due to weirdass WordPress  bullcrap, that’s just annoying.

If you try to comment from here on and it gives you any trouble, let me know:

A not-uncommon plot device is to have Our Hero suddenly sent back in time to his own past. Often this comes as a result of “magic,” and results in the memories of, say, a 40-year-old man awakening in the body of his sixteen-year-old self. Hijinks ensue, where Our Hero, whose life has been a disappointment or a disaster, uses his knowledge of where he went wrong to make better choices next time. Usually Our Hero is not someone who planned to travel in time via either science or magic, but Just Some Guy who got sent into the past through accident or some caprice of a supernatural being or artifact.

As wish fulfillment fantasy, this can of course be an appealing notion. I’d certainly like to be able to back things up a bit and make different decisions based on what I’ve learned. But there are definite problems that I haven’t seen touched on too often in such tales.

Right from the outset I’ll point out that the whole idea is of course ludicrous. If, tomorrow, I woke up with my current set of memories, but in my high school body on, say, October 7, 1986, my first thought isn’t going to be to wonder what interesting space-time event caused that. No, I am going to be pretty well convinced that my brain has finally broken, and that I’ve gone *insane.* It seems to me that going back in time to your younger body is *less* likely than you going back in time *bodily,* so that there is both a 40-year-old and a 16-year-old version of yourself side-by-side. But, let’s suspend disbelief in order to allow the story to continue.

I’ve often wondered about doing just this, what I would do, who I would tell what, that sort of thing. The assumption always is that I could avoid mistakes that I made, change relationships that worked out wrong, prevent other people from making the mistakes that they wound up making, and so on. But the engineer in me almost always immediately leaps to all the *problems.* And there are some serious ones.

The first obvious problem is that if you go back to your teen years (where a good fraction of such stories seem to go), who the hell is going to believe you? If you tell people but cannot convince them, they will think you a liar or insane. This would be a retrograde step, and could result in you being chucked into a looney bin for the rest of your life. So you’d have to carefully consider who to bring in, and how.

Second: I don’t know about y’all, but if I suddenly woke up on some random high school day, I’d be in some *serious* trouble in attempting to re-integrate. What was my class schedule? I have no idea. What was my locker number? No idea. Locker combination? No idea. What were my teachers names? Only a fragmentary list remains. How about homework? Papers I needed to finish?

These may seem fairly trivial compared to the whole idea of time travel… but if you are in high school and suddenly cannot carry out the most basic functions of your normal day, you’re in trouble.  Because even though you might have a college education… you can’t prove it. Your Masters Degree in Quantum Mechanics or your PhD in Afrocentric Lesbian Quadriplegic  Studies no longer exist. If your plans for changing your future require you to have a college degree, you still need to get your high school degree, and all of a sudden there’s a serious roadblock.

I found high school largely pretty boring the *first* time. I shudder to imagine the dreariness that would ensue if I had to read those awful novels and write crappy reports on them *again.* And today, I consider myself a passably good draftsman. Back in the day, I won some award or other in a state drafting competition (went to state competition, came in nowhere). But today, that drafting is all done on AutoCAD and the like. T-Squares? Pens? Hand-lettering? Gah. So plowing through the sheer mechanics of high school again would be problematic. Not to mention dealing with students and their “issues” that now would seem monumentally trivial. So you’d likely find yourself something of a social pariah even if you kept your time traveler status to yourself.

And after high school comes college. Do you go the same route or some other route? If the same route, you know what you were good at, what you weren’t. I’d know that I’d have to bang my head on the wall of calculus I and III, and I guess I’d try to find a way to slog through them more effectively. But you might decide to, instead, go some wholly different route. Once you do that, though, you no longer have much useful wisdom, and you’re starting from scratch.

Back to the Future II” included the idea of someone using their knowledge of the future – in this case, a stolen copy of a history of sports scores – in order to make themselves immensely rich. But with the younger-self version… you have to rely purely on your memory to do that. And what would you use? I don’t give a damn about sports, so I have no data on what team won what game with what score. So no sports betting for me. Other people, though, may well have that information memorized, and thus they could potentially do well. Lotteries are of  course of no value… I have no knowledge of what numbers come up where or when, and I seriously doubt anyone else does either. Some historical events of course could be bet on… who is going to run for President, who’s going to run for VP, and who’s going to win. But these only come along just so often. What movies are going to be big hits, and which ones are going to bomb, you may know. Do you know how to profit from that? The Internet Boom of course provides some opportunities for investing, assuming you arrive in a timeframe meaningful for that (reawakening  as your 16-year-old self in 1954 negates that possibility). Of course, some investment strategies may work negatively… trying to get in on the ground floor of Amazon or Google or Facebook might cause them to make different decisions, with the result being that the company flops. So… good job, I guess.

And how about The One That Got Away? OK, presumably you have some idea where things went wrong. And you are now well positioned to prevent that. But The Other One is still a 16-year-old mind in a 16-year-old body, while you’re  a 4o-year-old mind in a  16-year-old body. And the difference between a 16 year old and even a 24 year old version of the same person can be pretty substantial. The 40 year old you might find that you cannot *stand* the 16 year old Other. The 16 year old Other may find the suddenly changed version of you (whether or not You and Other had actually met at 16) seriously odd or creepy. So in order to correct a relationship what done gone wrong, you’d have to get the relationship going in the first place… and this may require some substantial acting on your part. You might have to act much less mature than you actually feel, which would be a strain… and you’d have to act like the immature and probably vapid Other is actually interesting. And, hell, let’s face it, you’d have to act like the current popular culture is still of interest to you. “Oh, yeah… A Flock of Seagulls. Awesome,” or “Sure, Right Said Fred will last forever.” You might well have to put yourself through years of torture with someone you don’t like in order to be with them, years later, when they mature into someone you *will* like. But by that point, you’ve spent so long lying and torturing yourself that you well and truly cannot stand them. So… good job, I guess.

Time travel fantasies of this kind tend to focus on either the big things (preventing the Japanese attack on Pearl Harbor, say), or gloss over all the problems and go straight to Our Hero setting all the wrong things right. It could be that my memory just isn’t that good, but it seems that the fictional time travelers always seem to have remarkable memories of the things going on in their lives decades earlier, and somehow skip right over the serious problems that I foresee.

Just got back from a little day-trip. The focus of the trip lasted only a half hour or so, but that, coupled with some walking around before and after, resulted in about 1,300 photos.

Hint: this can be seen as an update or sequel to something  from almost a year and a half ago…

The “Occupy Wall Street” fleabaggers have gotten the endorsement I’m sure they were looking for:

American Nazi Party Endorses Occupy Wall Street‘s ’Courage,‘ Tells Members to Support Protests and Fight ’Judeo-Capitalist Banksters’

National Socialists supporting International Socialists. Hardly a surprise; the goals are pretty much the same, just with some of the labels swapped around.
