When it's turned sideways it won't fit back out so it holds the container in place.

The containers have the female part of the lock incorporated into their steel frames at the corners. So when you stack them, the locks engage, and they become mechanically bound to one another in series. They don't bind horizontally (side to side), however, so you can get the weird accordion effect you see on the ship that started this discussion.

Oklahoma, at least around OKC and Norman, is so flat and devoid of vegetation that it makes a frozen lake surface look like Denver.

There's a bit of leeway on that, shipping containers are banged around a ton and if tolerances were that tight they'd constantly need to be replacing poo poo. There can be pretty loose tolerances in that way for it to still work fine.

Phanatic posted:Cirrus is, I believe, the only aircraft manufacturer who puts chutes on their planes. Initially, the safety record of them wasn't good. Deploying the chute probably saves your life, and almost certainly totals the airplane. Even the seats are aluminum honeycombs that collapse on impact. So you did wind up with pilots who tried to land an unrecoverable airplane instead of pulling the chute handle, and died. One of the things that get missed alot when compared to cars is that the training never really stops for pilots. You still have to check in once in a while for exams. The paperwork has to be updated and submitted. If there is something wrong with the plane you not allowed to fix it yourself. The significant cost of owning one and the inability to park it like a boat or on the shoulder means most are aware that yes, I am responsible for controlling this contraption. Losing your license is a real thing compared to cars. There are free workshops to get better or more skills. Using a different piece of equipment means a briefing or rating. All this and more allows Cirrus plus others to educate pilots after the purchase. When was the last time a car company communicated to you that wasn't a recall or advertising, to give you information and training to better drive your car?

Collateral Damage posted:Are there any current planes larger than fighters that are capable of supercruise? On the Soviet / Russian side, the Tu-22M is described as a "supersonic ... bomber" and is listed as in operation. I don't know how militarily useful that arbitrary distinction really is. There's a fair bit of fuel you need to burn to get past that magic number, but Mach 1.1 is not dramatically quicker than Mach 0.95. It's not going to protect you from a missile capable of Mach 3.5, for example. The history of military aviation during the Cold War is full of examples of supersonic aircraft that never got past the prototype stage for various reasons, usually because of either a major accident or a change in government policy in the West, or unknown reasons in the USSR (wild guess: chief designer got sent to the gulag). Look up the TSR-2 and the XB-70 Valkyrie if you're interested. Those serve as good starting points for a long Wikipedia dive. I have too much poo poo to do today so I can't go for that dive, but somebody else please go in there and come back with harrowing tales of stupidity leading to fireballs. I'm sure there are plenty of those.

Subaru sends me a lot of poo poo including upcoming snow driving training, rally training, etc. I guess that counts as advertising though since I'd need to pay for it. I think they do sometimes have things they send out about "learn to get the most out of your entertainment system!" type stuff that's arguably training, but it's not at the level of what like Cirrus does no. Then again I didn't drop a quarter million on my WRX. I think they start to do that stuff if you spend that much on a car.

I don't know where you're all getting that a Cirrus only costs a quarter of a million dollars. A new SR22 ranges from $550,000 to $800,000. They are purchased by the kind of people who are cross-shopping against a beach house. 250 large is what you'll pay for a new base-model 172.

Looks like just spectacular incompetence at the intersection of design and construction: This was supposed to be a cable stayed bridge. Usually those are built in short sections starting at the tower and working toward the ends, so each section can be connected up to the cables that support all of its weight. Here, to minimize the amount of time the road had to be closed, the entire span was built next to the road and then moved into position and supported on the landing structures at the very tips, unsupported at any point in the 200 feet in between.  If it was capable of holding itself up in that configuration, it wouldn't have been designed as a cable bridge in the first place.

They literally tried to build the bridge deck BEFORE the supports. I could understand it if they had some big temporary supports between the lanes to hold it up while they build the whole essential cable part of the cable stayed bridge. Did they think the cables and tower were just for show? Did an engineer do some napkin math and determine the bridge would be strong enough on its own during construction, just not strong enough to be rated for use? Was there just so much pressure on the builders to minimize road closures because it's florida and cars can't ever be inconvenienced?

From looking at pictures the span that was put in place Saturday was only part of the final planned bridge so maybe the design considered this section stable and cables weren’t considered required until later in construction when more had been added. I’m sure we we will find out who hosed up eventually.

I've seen rush job pedestrian overpasses, they're simple concrete or metal bridges designed to be supported on both ends. The fact that this was cable-stayed was most likely to make the project pretty and interesting rather than some simple metal girder or concrete beam. But "rush job" and "fancy over-engineered aesthetic design" don't really mix.

But "rush job" and "fancy over-engineered aesthetic design" don't really mix. At 174 feet with no arching to transfer the load to the end points, I am in no way surprised it collapsed. Even with an arch I would expect a central pylon over that length. A cable-stayed bridge of this size is not "to look pretty". Those cables are an integral part of supporting a span like this. The tower should have been the first element erected, and then cabling attached as the span is moved into place for this type of bridge. I mean, it's been decades since I've taken Statics, but this much I remember.
