    FIU Bridge Update - New Bridge Has Broken Ground

    Agreed. I, too, need a bit of colour. Perhaps I could get a federal grant for a new Corvette to replace my sad old Toyota. The "colour" would be a very slightly orangish yellow. spsalso

    FIU Bridge Update - New Bridge Has Broken Ground

    Oh. There is not utmost clarity in the costs related to the fallen bridge. Wikipedia shows the bridge costing $9 million, and the overall project $14.2 million. The bridge is the thingy that spans a distance. Abutments hold it up, and COULD be considered part of the bridge. Elevators are...

    FIU Bridge Update - New Bridge Has Broken Ground

    I was incorrectly assuming a mid-span pier placed in the median strip. I see that that won't work. So, a single 200' span instead of two 100'. I'm not following your comment about "two sets of lifts at either end". What is that? And what does it have to do with the price of the bridge...

    FIU Bridge Update - New Bridge Has Broken Ground

    That's the benefit of using OPM (Other People's Money). In this case, the bottomless pit of Federal money. "Are you sure that'll be enough?" The Wikipedia page says the bridge cost $9 million. That's the one that failed. According to this site...

    North Korean Ship Fails/Capsizes at Launch in Front of Kim

    Sorta reminiscent of a dog thinking he's hiding behind a tree. Except the dog's kinda cute, doing it. spsalso

    Mexican navy tall ship slams into Brooklyn Bridge

    I suggest this video: latest Sal Mercogliano video It's looking like there might have been a failure in the controls for the variable pitch propeller. or MAYBE a crew failure in the prop operation. spsalso

    Mexican navy tall ship slams into Brooklyn Bridge

    Well, we've found out that a dragging anchor works very nicely for ripping up undersea cables. And you don't even notice. So they say. spsalso

    Bayesian interim report

    I am left wondering why "they" didn't drop the keel, as soon as they noticed a weather threat. spsalso

    Mexican navy tall ship slams into Brooklyn Bridge

    Here's specs on the tug: https://www.mcallistertowing.com/our-fleet/charles-mcallister Considering the circumstances (tidal flow, bridge nearby, no tugs attached, no thrusters, low-power engine), one can wonder why no one was in position at the anchors. I'd hate to be the one to say: "I...

    Mexican navy tall ship slams into Brooklyn Bridge

    It's been noted by Sal Mercogliano that there was a wake and "bow" wave at the stern of the ship--you can see it in the video as it approaches land. If it was riding with the current, and no power, that would not happen. While there was wind, it didn't look that strong. To me. So. Sal...

    Clearwater condo evacuated

    If the column lost support because of removal of the slab, wouldn't the column have dropped, and wouldn't there be cracking in the ceiling as IT dropped? spsalso

    Clearwater condo evacuated

    I'm sure the original building inspector thought it entirely adequate. So, too, the government agency that employed and directed him. Be assured they take these things Very Seriously. I wonder if a PE was possibly involved in this project. Maybe. It could happen. Say, are there actually...

    FIU Bridge Update - New Bridge Has Broken Ground

    Yeah. THAT one would have been a great choice. Although I don't think the FIU one is "goofy", I think it's "stupid". spsalso

    FIU Bridge Update - New Bridge Has Broken Ground

    I'm probably just being a fuddy duddy, but: I'd make the roof wider than the walkway. That way you could do a better job of keeping the rain (does it rain in Florida?) off of the pedestrians. I'm sure the "stakeholders" would think that a nice convenience. It's sorta like having the roof...

    FIU Bridge Update - New Bridge Has Broken Ground

    So they're replacing a crosswalk with a bridge. Again. For $37 million dollars. It's true that I've seen a goodly number of college students walk into an intersection without looking first for approaching traffic. Perhaps that's the inspiration. I wonder if it will challenge the...

    Semi Hauling Excavator Hits Bridge over I-10 in New Mexico

    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...

    NTSB Recommends 68 Bridges in US be Evaluated for Risk of Collapse from Vessel Strike

    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...

    Attempted Taxiway Take off

    This link should work: https://en.wikipedia.org/wiki/Air_Canada_Flight_759 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...

    AA jet and Military helicopter collide over Potomac

    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...

    AA jet and Military helicopter collide over Potomac

    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...
