I join the non-engineers in solving engineering problems!

There was a terrible accident at a bridge in Baltimore — it was struck by a container ship and collapsed horrifically. I didn’t think I had anything to contribute to the discussion. Minnesota had a terrible bridge collapse back in 2007, but that was a consequence of neglect and failure to maintain critical infrastructure. This event seems to be completely different.

But then I looked at the news and noticed that a lot of idiots are throwing out explanations. Hey, I have no engineering expertise, know nothing about bridge construction, but have ridden on a ship a few times, therefore I’m just as qualified as the Fox News team or Victor Davis Hansen, or some guy who has appeared on Ancient Aliens, therefore I should opine.

You should look at how they’re explaining the crash.

A non-exhaustive list of things that are getting blamed for the bridge collapse on Telegram and X include: President Joe Biden, Hamas, ISIS, P Diddy, Nickelodeon, India, former President Barack Obama, Islam, aliens, Sri Lanka, the World Economic Forum, the United Nations, Wokeness, Ukraine, foreign aid, the CIA, Jewish people, Israel, Russia, China, Iran, Covid vaccines, DEI, immigrants, Black people and lockdowns.

The Francis Scott Key truss bridge actually collapsed when the MV Dali cargo ship collided with one of the bridge supports. Six construction workers, who were filling potholes on the bridge at the time, are presumed dead. The ship is owned by Singapore-based Grace Ocean Private Ltd, and the 22-person crew were all Indian. The ship was on route to Colombo, Sri Lanka at the time of the accident.

This did not stop people from “asking questions” about the incident, a frequent conspiracist response to major events. And though conspiracy theorists are having a hard time pinpointing exactly what conspiracy caused the collapse, the one thing they do agree on is that this incident is a “black swan event.” The term “black swan event” has been around for decades, and is used to describe a major global event (typically in the financial markets) that can cause significant damage to a country’s economy. But in recent years, the term has been co-opted by the conspiracy minded to explain an event triggered by the so-called deep state that would signal an imminent revolution, a third world war, or some other apocalyptic catastrophe.

Man, a lot of them blame DEI, which seems to be the go-to excuse on the right wing for everything. I don’t get it, though. This ship was crewed by Indians, and the bridge, the victim in this collision, was crewed by immigrant labor, so we can’t blame the magic word “DEI” for that. Fortunately, I, a non-engineer, am here to explain the problem and how to fix it.

The bridge was clearly under-engineered. It crumpled so easily with a slight bump! Clearly, those pilings (or whatever bridge people call them — you know, the bits sticking up out of the water holding up the road) were flimsy and inadequate, and need to be built back stronger. As it is, they probably wouldn’t hold up if they were slammed by a 6-ton wrecking ball, so it’s back to drawing board, and they need to be built with the goal of standing up to the force of a 100,000 ton wrecking ball traveling at 8 knots. Easy, right? I am also not a physicist, so I will leave it to the smarter people here to calculate the amount of force it needs to resist. It’s something like , where you have to multiply and divide and solve for F, way above my pay grade.

So, yeah, just build bridges that are that strong.

I’m not sure where Wokeness or P Diddy or vaccines fit into the equation. We might need to recruit some social scientists to work on the bridge redesign team, and I’m definitely not smart enough for that stuff.

Or I could stand back and let competent people find solutions, which probably don’t involve impossibly strong structures or firing people with the wrong skin color, but where’s the fun in that?
