Piggyback Planes

SFOGuy says...

Well, they're much farther apart than they appear...and yet, not far enough lol.
One of the reasons SFO has such horrendous weather delays is that the runways are JUST close enough together that the FAA does not currently allow for side by side instrument approaches to them in bad weather. So, what is a "two lane" airport suddenly becomes a "one lane" airport as soon as the fog, clouds, or stuff shows up. And then the delays become ridiculous

Sulfur Mound Fire

bremnet says...

The usual recourse is water fog (vs water stream that just tends to raise more dust and spread more fire). If it's a large mound of extracted sulphur from e.g. sour gas fields, we used to just push more sulphur on top if the fire and that'd snuff it out.

Wow. What do you even do? Pour sand on it?

Seeing through fog

oritteropo says...

The Cadillac system, offered between 2000 and 2004, used a passive infrared camera for night vision, which was displayed on the windscreen using a heads up display. Actually a whole list of expensive cars have had this option available since Cadillac and Raytheon introduced it.

I don't think it would necessarily work well in heavy fog, which is what this new research is targeting.

newtboy said:

Cool, but I recall Cadillac offering a similar system years ago that superimposed objects on the windshield. It certainly seemed better than human vision on the commercials, but I've never seen it in action.

Stress Testing Giant Sequoias | That's Amazing

newtboy says...

I'm disappointed that he neglected to mention that sequoia can get a huge percentage of their water from fog. They are so tall that to pull water up from the roots doesn't cut it, the tugor pressure needed to pump enough water 300' up is immense, far beyond xylem and phloem. That makes them more drought resistant than other types of trees, and explains why they are found only in places that get fog regularly.

Kinda oddly a fail and a win at the same time. No one died

Mekanikal says...

I read there was a malfunction in the guard arms and they didn't come down. Due to the weather the truck driver looked right but didn't see the train because of fog and rain. A truck that size isn't very quick and you get what we see here. Good to know everyone is ok.

Tesla Predicts a 2 Car Crash Ahead of Driver

Curious says...

Tesla enthusiast here. The Tesla vehicle is able to use its front-mounted radar to track one car beyond the car in front of it. How does it do this? It bounces the radar signal off the street underneath the first car. In this case the Tesla could determine the position and velocity of two vehicles in front of it and it predicted a collision, sounded the alarm, and applied the brakes.

So no, it's not that the cameras are tracking objects through another vehicle's windows (at least not yet). Radar can also see though zero-visibility conditions like snow and fog.

Smoke on the Water

The fog catcher who brings water to the poor - BBC News

newtboy says...

I remember seeing a documentary about someone experimenting with fog collecting with netting in that area years and years ago. They have little rain, no lakes, but fog almost daily, so it seemed a perfect solution. I'm glad to see that it's being implemented, even if only on such a small scale.
It shouldn't take much to filter that water enough to drink it, then they would have (near) free water on tap instead of waiting for a water system that isn't coming.

We usually get a few weeks right at or below freezing...but last year barely a few days (nights) reached freezing, and back up to mid 50's during the day.
I have a greenhouse, I'll try a few in pots I can put inside when it freezes.
Another problem we have is lack of sun. Our local airport (Arcata) was built to train pilots for fog landing, being the most consistently foggy place in the U.S.. there's little I can do if we have a foggy year.
The pineapple is in a 1/2 barrel that I brought inside for winter. The pineapple took 18 months to ripen, and was 8 bites in total, but that still counts imo. ;-)

oritteropo said:

If you could grow a pineapple you should be able to grow oranges and lemons. We have roughly socal weather here, and have no problems with either... but it never freezes here. You would need to protect the tree from freezing if you have temperatures much below 0°C for more than 10 hours at a time (google didn't answer that question for nocal, my query must've been off) but planting against a south facing brick or stone wall would help if it's marginal (obviously we'd be using a north facing wall).

p.s. worked out the right query, and nocal looks ok on the coast, and even OR and WA, but going further north to BC looked a bit iffy... but then people do manage it - http://www.5dollardinners.com/oranges-from-canada/

The conversation of those two is glorious. He's the stereotypical "hold my beer and watch this"-kinda guy while she's scared shitless.

That said, there was a pair of tornadoes in Minden as well, maybe two weeks ago. That's 60km from where I live and I can't remember ever hearing about tornadoes, no matter how small, in this area.

Ah, well. Weather's bonkers anyway. Massive downpours for three days straight, followed by clear, blue skies and 30°C yesterday. This morning, fog. Some consistency would be nice...

What Happens If You Drop 30 lb of Dry Ice in a Pool

newtboy says...

Good idea, terrible execution.
My brother had a kegger for his 16th birthday party and we heated the pool up to 105 deg, then threw 30-40 lbs of dry ice in. That was much better than this try on an infinity pool. The pool we had was an in ground pool, and the yard had a wood fence, so the fog stuck around and built up to 2-3ft deep. Lots of people went swimming while it boiled, I suppose we're lucky we didn't have any issues from too much CO2. Good times, good times.

The Most Costly Joke in History

transmorpher says...

I have not agreed that my position is wrong on the performance and capability designs of the F-35 and modern air combat. Please read the rest of my post above.... I'm still saying that dogfights have ended with WW1. I've never said we don't need ANY dog fighting capabilities. I'm saying that it's never the primary design idea of a modern fighter jet. You still have a cannon for back up. Just like soldiers have a side arm and a knife. Just in case you do get caught with your pants down or the main weapon fails at a critical moment.

I have agreed on the waste of money aspect of course. I'll also agree that if test goals are being downsized to accommodate flaws, then that's just terrible. If it's not able to perform to it's design then it's useless.

The F-4 != F-35. I can see why people draw parallels. But that only works if you ignore that absolutely everything on the planes is different, the adversaries are different, and stealth is requirement for survivability. You don't use stealth planes in the way you use an non stealth plane. Have you ever heard of a sniper wearing a ghillie suit run across the open battlefield with a sword or pistol? There were so many tactical mistakes in Vietnam as well. The conditions in which that article talks about are also different. Those planes were flying low and slow for a bombing run. Because they didn't have laser, gps guided bombs, infrared fire and forget air to ground missiles or cruise missiles back in those days. You don't get fog at 40,000 feet. They had to fly that low to get a visual identification of their bombing target. That does not happen anymore either. You scream past at mach 1 above the clouds and the bomb hits where it was programmed to hit. Also the phantoms missiles were unrelaiable. That hasn't been the case since the 80s. And their training was poor. None of that is true these days, and has not been true since the 80s either. That's why every single fighter plane apart from the F-16 (which is made mostly as an export product anyway) has been created to fight at long range primarily. The F-15 which is the main air superiority fighter for the US, is heavy and has a worse maneuverability than any Russian plane. But it's still the most feared plane, with no loses in combat. The article you linked even says that. So it's basically contradicting itself. At the start it says, F-4's lost because they couldn't maneuver, and ends with therefore the US made the F-15 which has worse maneuverability than the Russian planes lol.



Edit: Cracked.com doesn't count as a reputable source for anything, including basic sentences, spelling and punctuation.

Edit2: Here is an article from an actual F-35 pilot that says the F-35 dog fights better than a F-16 since they keep tuning the fly-by-wire parameters. http://theaviationist.com/2016/03/01/heres-what-ive-learned-so-far-dogfighting-in-the-f-35-a-jsf-pilot-first-hand-account/

So even if it came to a dogfighting encounter, the F-35 is still the best plane in the US arsenal for dogfighting.

newtboy said:

Well there YOU go.
I'm not sure if you're aware, but WW1 ended well over 25 years ago, so your repeated contention that 'dogfights ended in ww1' so we don't need any dogfighting capabilities is clearly 100% wrong. I hope you'll stop repeating it now, as it's ridiculously annoying to have a conversation with someone who agrees that their position is wrong, but continues to stand on that position nevertheless.
http://www.realcleardefense.com/articles/2015/07/06/usaf_promised_the_f-4_and_f-35_would_never_dogfight_108180.html
and (the last one mentioned here is INSANE)
http://www.cracked.com/article_19396_5-aerial-battles-that-put-top-gun-to-shame.html

I hope you've also arrived at the position now that, if they have to change the testing parameters/minimum acceptable requirements to turn massive fails into 'success' that it fails miserably and can't possibly ever be prepared for real deployment and has become nothing but a massively expensive, poorly preforming jobs program.

Rumsfeld held to account. Too many great quotes to pick one

Fairbs says...

You might be interested in the movie, The Fog of War. I think that's the title. It's about the morality of making these types of decisions.

MilkmanDan said:

I found Colbert's question about "unknown knowns" the most interesting, but here's the thing:

Bush was the Commander in Chief. He didn't present their "intelligence evidence" of Iraq's WMDs to the American people because he *had* to. He tells the military what to do, they do it; the people don't get "veto rights". The only reason he presented it to the American people (I still remember watching Colin Powell show satellite photos etc.) was to shore up votes for his re-election. Which is exactly what any politician would do in that situation -- make a decision, and present that decision in the best possible light to the voters.

In other words, when Bush et al. were presenting that stuff to us, they weren't selling the actual invasion itself to us. They were selling us an image of their own legitimacy and competence. Viewed like that, of course they aren't going to inform us of those "unknown knowns"; it would shatter the image of them confidently and capably doing what they knew they had to do -- which was the actual point of it (selling that image to us, I mean).


I was sold, at the time. As were most (but not all) Americans, including many many people much older and wiser than I was (and am). I now agree that the invasion was a colossal mistake and that Bush's presidency in general was rather disastrous. BUT, that being said, I think it is problematic to hold these kinds of decisions against a president beyond a certain point.

FDR decided to drop two atom bombs on Japan rather than continuing with conventional warfare and risking many more American (and Japanese) lives with an invasion. Many people have questioned (and continue to question) that decision. But FDR was there. He was the Commander in Chief, he had some facts and plenty of unverifiable information and suggestions from his cabinet and intelligence sources of the time, and he made the decision.

I don't envy people in power who have to make weighty decisions like that based on incomplete information, only to have people question those decisions by citing information that they didn't have at the time. For the rest of their lives.

Amazing Fog Waterfall

artician says...

There is a similar phenomenon in the San Francisco Bay Area in California. Around dusk every day in the springtime, a 'tidal wave' of fog flowing eastward from the coast would hit the western foothills of the peninsula, and arc gracefully over the 280 freeway like a massive, slow-motion crash of water. From 20 miles away it looks like a tidal wave, capable of wiping out all of silicon valley, is just frozen in place at the edge of civilization. Up close, it's like surfing your car through the barrel of an enormous wave.
It's one of the most beautiful things I've ever seen in my life, and it happens almost daily there.
