Plane Ran Out of Fuel at 41,000 Feet. Here's What Happened.

CrushBug says...

OK, hold the fucking phone here. This video is just a disaster. It is flippant and glossing over the facts of what actually happened. This story is a favorite of mine, so I have done a lot a reading on it.

This happened in 1983 (36 years ago).

>> Do planes seriously not have a fuel gauge?

There is specifically a digital fuel gauge processor on that plane, and it was malfunctioning. There was an inductor coil that wasn't properly soldered onto the circuit board. At that time, planes were allowed to fly without a functioning digital fuel gauge as long as there was a manual check of the fuel in tanks and the computer was told the starting fuel.

The problem is that fuel trucks pump by volume and planes measure fuel by weight. The fueling truck converted the volume to kilograms and then converted to pounds. He should not have used both. In 1983 ground crews were used to converting volume to pounds. The 767 was the first plane in Air Canada's fleet to have metric fuel gauges.

The line in the video "the flight crew approved of the fuel without noticing the error" glosses over how it is actually done. The pilot was passed a form that contained the numbers and calculations from the ground crew that stated that 22,300 kg of fuel was loaded on the plane. The math was wrong, but unless the pilots re-did the numbers by hand, there wouldn't be anything to jump out at them. He accepted the form and punched those numbers in to the computer.

The 767 was one of the first planes to eliminate the Flight Engineer position and replace it with a computer. There was no clear owner as to who does the fuel calc in this situation. In this case, it fell to the ground crew.

>> I would hope there is a nit more of a warning system than the engines shutting off.

If there was a functional digital fuel gauge, it would have showed them missing half their fuel from the start, and the error would have been caught. Because there wasn't, the computer was calculating and displaying the amount of fuel based on an incorrect start value.

That is another problem with this video. It states that "they didn't even think about it until ... and an alarm went off signalling that their left engine had quit working."

Fuck you, narrator asshole.

In this case, low fuel pump pressure warnings were firing off before the engines shut down. They were investigating why they would be getting these low pressure warnings when their calculated fuel values (based on the original error) showed that they had enough fuel.

>> I can't believe the pilot's were given an award for causing an avoidable accident.

The pilots did not cause it. They followed all the proper procedures applicable at that time, 1983. It was only due to their skill and quick thinking that the pilots landed the plane without any serious injuries to passengers.

They ran simulations in Vancouver of this exact fuel and flight situation and all the crews that ran this simulation crashed their planes.

"Bad math can kill you." Flippant, correct, but still not quite applicable to this situation. Air Canada did not provide any conversion training for dealing with kilograms and the 767. Not the ground crew, nor the pilots, were trained how to handle it. They were expected to "figure it out". That, and the elimination of the Flight Engineer position, set these situations up for disaster.

The sky is not the limit

I've become torn about drone nature videos.

On the one hand, the views they can get are unique and stunning, the adrenaline pumping rollercoaster rides through impossible obstacle courses are heart pounding.
On the other, I'm all too aware of the efforts people make to have a single day in the peaceful majesty of nature, and having what sounds like a fleet of leaf blowers hovering overhead, whirring back and forth through the scene can ruin the experience completely.

I really believe there should be designated days/weeks when drones are allowed in public parks, reserves, preserves, wilderness areas, etc and they should be banned other times to make it fair for everyone.

I was a repeated victim of drone pollution in Iceland.

No joking around about the turkey

My_design says...

I brined a 14 pound turkey and roasted it in a convection oven after putting rosemary, sage and thyme butter under the skin. Took it to my mother-in-laws. She usually cooks, now I'm a little worried I showed her up... But my wife said it was the best she'd ever had and I was happy with it.

Collapsing sidewalk swallows two women whole

SFOGuy says...

Uh, swallowed and then crushed by the concrete that collapses on them.
Lucky it was minor injuries; looks like hundred of pounds of concrete.

Great post fight interview

My_design says...

I loved this fight! Lewis looked like he was falling over, but every single punch he threw had everything in it, all 265 pounds and every bit of force he could muster. All he needed to do was land a punch...When it finally happened, it was amazing. Knocked the mouthpiece right out of Drago's mouth. Then came the interview and it got even better!

Butchers Attempt to Make a Giant Beef Porchetta

Ashenkase says...

So, some silly math. The cost of a side of beef in Canada is approximately $1125:

A side of beef (½ beef) is sold by the hanging weight. Hanging weight is the weight of the animal before it is trimmed and cut. The approximate hanging weight of a side is 300 lbs. The cost is $4.75/lb cut and wrapped. Therefore the approximate cost of a side of beef is $1125. On a 300 lb side, you will take home approximately 200 pounds of actual meat. A side of beef is cut to your specifications.

The roast was 60 pounds which is 30% of 200 pounds.

So $1125 * 30% = $337.50 CDN

or

$256.74 US


That is one roast you do not want to fuck up in the oven.

Pink Floyd Clare Torry "The Great Gig in the Sky" interview

ChaosEngine says...

She had such an amazing voice.

This doesn't tell the whole story though. In 2004, she sued Pink Floyd and EMI for songwriting royalties. Given that she was originally paid 30 pounds, I think it's fair to say that she deserved a cut of the squillions of dollars they made of this. They eventually settled out of court for an undisclosed sum, but I hope it was at least 6 figures, because god damn, she NAILED it.

Brilliant song. Start at the one minute mark to hear Clare sing

Test firing a custom 4 gauge shotgun

radx says...

For people unfamiliar with "gauge": 4(12) gauge basically means that your barrel diameter is equal to the diameter of a lead ball weighing 1/4(1/12) pound.

In case of this 4 gauge shotgun, we're talking about a barrel diameter of almost 27mm.

44 Wild Hogs caught all at once

I had to watch it with the volume turned off. I wonder what the price per pound for wild caught pork is?

Good trap, horrible *commercial ...way too long for what it is.
I wonder if they have something for gophers.

I just now saw this. My yahoo email account sometimes disappears things on me. I lost another email about the same time.

I absolutely agree with everything you say. Biology is biology. There are differences. Sex is in the workplace, of course, and women bring it there.

I can agree with all these things, and still be creeped out by the indulgence, the wallowing, of only hiring very attractive women.

There is a long history of that in America, and it was creepy then, too. Stewardesses and what they were subjected to in the workplace is a great example. They would lose their -- THEIR WORK -- if they gained five pounds, is an example of really inappropriate use of a woman's appearance as a job qualification. These people are responsible for the safety of the passengers if a tragedy strikes. I love reading stories about how women are heroes and professional when an accident happens.

A shooting range is not a strip club. Wanting to be surrounded by women in your business who COULD work in a strip club is creepy.

Creepy really isn't the right word. It is shorthand for a complex interplay of gender roles and abuses and complicity that is endemic in our culture. I just like the way it feels in my mouth -- I found that Japanese word for it that perfectly explains my pleasure in using it. I am still pleased to know that word exists.

Gitaigo: Onomatopoeia that describes states of being, not sounds.

Creepy perfectly feels like my state of being around this video.

We are all biological beings who like to look at pretty people. Tall men make more money. Attractive people of both genders make more money. We will never be free from those responses.

But lets keep it unconscious, shall we? Let us work to be better human beings than people who reduce ourselves to walking genitalia looking for constant stimulation.

The rest of your points... yeah. I'm right with you. I am not someone who criticizes men for "looking." I find myself looking and I'm pretty firmly on the hetero side of things.

It came up the other day on a hike through the woods. A woman passed me wearing some sort of body hugging stretch pants. There was natural jiggling from her movements, which caught my eye. I found myself staring, I became aware of how perfectly proportioned she was, and how the rest of her was lovely in every aspect (I had seen her a few moments before, walking in a different direction.) I almost called out to my friends -- my god, that is the most beautiful woman. All triggered by a chance glance at an objectively beautiful rear-end.

Biology. It happens. I have no problem with it.

And those shooting range owners want to stimulate that reaction in the workplace, 100% of the time. And that, my friend, is creepy.

Asmo said:

I was responding to your comments, as I understood them, and if I got the wrong impression, I apologise. But I think it's somewhat blinkered to say that it's men that bring sex in to the workplace. eg. Most of the young ladies that work in the same building as me wear short skirts or tight pants, lots of decolletage on display etc. That is absolutely their right as long as they meet the dress code of their employer, but it certainly brings sex appeal firmly in to the limelight.

Unfortunately, while men are seen as rather simple creatures biologically when it comes to sex, there is more than meets the eye. The science certainly isn't conclusive, but there is a lot of evidence pointing to desire being a function of the amygdala, which is strongly stimulated by visuals in men. The following article is a pop news summary of a longer (and fairly dry) study which I couldn't find an non-subscription version of, which compares brain activity in response to viewing porn images for both men and women.

http://www.nytimes.com/2004/03/16/health/in-sex-brain-studies-show-la-difference-still-holds.html

Women still get aroused by the images, but the desire that is evoked in the male amygdala is not replicated in the female. Hence men tend to respond far better to objectification than women do. There are other results with further delve the difference between male and female sexuality, and it's not surprising that society as a whole has been molded by our biology.

Probably also explains, at least somewhat, why men (myself included) find it hard to accept criticism for something that comes naturally to most of us. Few men would go to a public place with the express purpose of leering at attractive women, but almost all men (at least the straight ones) will find themselves gazing for longer than perhaps polite at certain women that catch our eye. That is not to take away from the fact that we are generally in charge of our actions, but it certainly adds an imperative that is less about being creepy and more about our biology.

Shark

jmd says...

I belive part of the trick is the fact that the screen is not that clear to begin with. It looked like a refracted window in a fairly murky water with little visibility, and at first I figured it was a lens trick so the aquatic life couldn't see in. The second part of the trick is "expecting something but in reality expecting to get nothing" when you pound on the glass, and suddenly SHARK.

AeroMechanical said:

Is there some kind of new technology or something going on here? I have difficulty believing anyone mistaking a flat display for a window no matter how good the picture is or how bad the viewer's depth perception is. This guy in particular was inspecting it and obviously trying to figure it out.

Vox: Why America still uses Fahrenheit

KimzSendai says...

I've lived in the US since 2013 ... I'm OK now with instantly "translating" to miles and feet and pounds and gallons in colloquial speech (at work we all use metric because I'm in science and tech with international collaboration), but Temperature??? I'm still in Celsius and can't adapt seem to adapt.
