Looking at the photos of the excavator, I do think that this piece of equipment was NOT railroad related.
While there are indeed railroad wheels present, the tracks appear to me to extend far below the level of the bottom of the wheel. This would make it useless on railroad track, because the...
I didn't find any mention of this in the Wikipedia page for the bridge.........
I do know that the western span was real-life tested in 2007 by the Cosco Busan, and passed with flying colors. Evaluation of that event may have concluded that that bridge was "adequately protected". Which it...
This link should work:

It didn't get reported because it didn't HAVE to be (see article).
Also note that the landing was around midnight.
Seems to me the planes on the ground (the ones that almost got hit) would have been facing the...
I believe it was mentioned earlier that there were quite a few close calls at this route intersection. And the FAA knew, or should have known, about it.
If that's the case, someone knew there was a dangerous situation, and did nothing. Or not enough to have adequate effect.
I was just...
So I'm wondering who's the person who could have decided and enforced that helicopters would NOT be allowed to pass near the airport flight path during its use.
Someone could and should have said "No, it's too dangerous."
And didn't.
(And I'm not talking about the ATC. Or either pilot. None...
Kinda "poetic", hitting it just below the clearance sign.
If'n I was a truck driver, I might not pay a LOT of attention when I'm hauling a standard height trailer. But did the driver not even consider that he was hauling a high load that might take special attention? Seems kinda obvious, when...
If it's not simple to transition from forward flight to hover quickly, maybe that operation should be started sooner.
I also recommend a dose of humility for public servants that think that their time is incredibly important, to the point of endangering that very public they serve. Perhaps...
Since runway 33 is lightly used, there would be minimal problems if helicopters ALWAYS had to stop a fly-through when a plane was due through that area.
It seems so obvious.
I wonder if a lot of Very Important People flew on this helicopter route. That could explain why it was unacceptable to...
There have been weekly reports on settlement of this building:

The latest one is dated July 29, 2024.
I wonder at the length of the latest "week".

Seems like the extractor of the oil under the property might be required to put it back--to "make him whole".
Sort of a corollary to the Hawaii story.

Twice, doing electrical work in San Francisco, I discovered that the old gas lighting lines in the ceiling were still live.
I proposed to one owner that they re-install the gas lights, but there was a lack of interest shown.
Last I looked, there was a working gas light at Heinhold's First and...
The article is such an interesting read.
The report cites 5 particular causes for the failure. Three of those were site conditions. There are those of us who feel that if you can't design for the site conditions, you should not take the job. And there are those of us who feel that if you...
Besides Sal with his "What is going on with shipping", there's also this guy, who seems pretty sharp:

As has been pointed out repeatedly in mass media, container ships have been getting larger and larger and HUGE-ER!
And that has been happening over the past 50 years, or so.
So, although it's a surprise to mass media, it wouldn't be a surprise to anyone dealing with ocean shipping. Like...
"Pretty sure piers are NOT designed for a fully loaded container ship to impact them, regardless of speed. Let's be more judicious on the whole "defective design" folks. Find a referenced standard and know what you're talking about, please."
Well, yeah. That's why they put fenders around them...
But the plume started before the second time the lights went off.
The lights came back on, the first time, at 2:23
The smoke plume started at 2:35
The lights went off the second time at 3:29
The plume was emitted until impact, or thereabouts.
By the way, Sal's doing his usual great job of...
In the video, a short while after the lights come back on the first time, there is a smoke plume out of the ship's stack, and it continues right up to the strike. I suspect the engine stopped, causing the lights to go out. Then it was restarted, with the plume signifying it had not settled...
It's my belief that one cannot quench harden brass.
I've just run into someone who insists it can be done. He says he's done it. "And my Professor of Metallurgy at Stevens even mentioned it in class when we were discussing brass vs. bronze."
Can someone come up with some documentation for...
Budd was building stainless passenger cars for years--since before WWII. Some are still around.
They likely didn't/don't get much salt exposure, though.
