AF 447’s breakup

This photoshopped image, by a commenter on this pilot’s forum, shows where the jet’s recovered vertical stabilizer apparently tore off–though whether in mid-air or on impact with the ocean is unknown. Meanwhile, previous notions of a superbolt of lightning frying the plane’s electronics apparently have been quashed by this updated meteorological analysis:

"* Lightning — Though in earlier versions of this study I had identified lightning as occurring in this mesoscale convective system, recent evidence from spaceborne and sferic sensors is pointing to the possibility that this system contained no lightning. Soundings do indicate moderate levels of instability, but there are indications in the literature that cumulonimbus clouds in oceanic equatorial regions entrain considerable quantities of drier, cooler air that dampen upward vertical motion in the lower portions of the storm, and in some way this reduces charge separation. In any case it does look fairly likely that we can rule out a lightning strike as being a factor in the A330 crash."

Indicating that turbulence within the storm apparently was the cause of the breakup at altitude unless there was some other factor which only analysis of the debris and/or the voice and data recordings could show.

I keep thinking back to the scenes of four pilots on separate flight decks unknowingly converging over the Amazon jungle. The Brazilian 737 pilots are sharing family photographs and flirting with a flight attendant. The American pilots in the Legacy biz jet are puzzling over how to operate a digital camera.

Both groups are at Flight Level 370 (37,000 feet) in normal mode: eyes inside the boat, letting their autopilots, transponders and collision-avoidance gear do the work while assuming that Air Traffic Control has things well in hand. But the Legacy’s transponder was on the blink and the controllers were asleep at the switch. Heckuva tale about what happened, here by journalist William Langewiesche.

His father’s classic, Stick and Rudder, led me to try flying back in 1974 in a Cessna 150 over South Florida. I was defeated practicing stalls above Boca Raton. Could not get the feel of falling out of my stomach or the picture of disaster out of my head. And it was too expensive. I stuck to scuba diving.

Boeing 787 Dreamliner

Fifty percent composite airframe (read plastic) and its first fly-by-wire is Boeing’s new airliner aborning. If, as some speculate, Air France 447 crashed into the Atlantic May 31 because of lightning-induced electrical problems with its computers, Boeing’s robotic Dreamliner could turn into its Nightmare–and ours. But, then, with half the airline market already invested in fly-by-wire Airbus, well… There’ll be plenty of pain to go around.

And to think I almost bought a Saturn

The Saturn was as close as I ever got to buying a GM product. Thank goodness I didn’t:

"…why Saturn flopped: The company had built a popular brand as a sort of feel-good anti-car–vaguely tractor-like, noisy, but made of semi-indestructible plastic by dedicated Tennessee workers and–unique in nearly all of GM–actually reliable. GM threw all this away and filled Saturn showrooms with cars designed to appeal to totally different buyers: rebadged mainstream Opels. They were OK, but creepily overstyled and not so reliable. End of explanation."

I drove a Ford pickup and a Jeep Cherokee, but otherwise have stuck to Volkswagens and Hondas. Whew.

Kofi Annan, warmist

I was willing to hear out the warmists on their Chicken Little bit until the Dictator’s Club weighed into it. I mean, come on, this is the outfit whose human rights council is run by tyrants who spend its time condemning Israel, while its Muslim members oppress women, gays, Christians, Jews, etc.

Now comes that paragon of corruption, Kofi Annan, issuing a phony little warmist addendum that draws a sneer from an expert that it is "a poster child for how to lie with statistics…worse than fiction." Isn’t it about time somebody figured out what’s going on here? It ain’t science, that’s for sure.

Air France Flight 447

Back in the day, Air Force pilots used to joke about "Air Chance." Some civilians still mutter darkly about the fly-by-wire, automated Airbus, although this apparently is its first major crash with passengers. For now the proposed explanation for the disappearance of Flight 447 over the mid-Atlantic, is severe turbulence, a possible lightning strike and hail damage.

Yet airliners are designed and pilots are trained to handle weather. It’s tempting, in this day of terrorism, to assume it was a bomb. Reports of simultaneous electrical failure and loss of cabin pressure suggest something like that. But they’ll have to find the wreckage, and hopefully the black (actually orange) flight data and voice recorders before we will ever know the cause for certain. If then.

Motorized cupholders

Henry Ford used to say you could have any color car you wanted as long as it was black. Now, course, you can have just about any color, but they all nag you to fasten your seat belt, close open doors, change the oil, etc. And the Japanese cupholders are better placed than Detroit’s. P.J. O’Rourke sums up why Detroit may not come back this time. Done in by the arrogance of government, labor unions and their own executive sloth. Once, they would have been missed. Now, maybe not. The romance of the automobile died too long ago. It’s just another appliance now.
