NO, it didn't - look at the current in the river - it's just that the boat didn't go all the way over, it righted itself - the ships bridge dragged along the bottom of the bridge - that's why the starboard stack and rails are all messed up

Charlie -

Look at the top of the bridge. Notice how in one set of pictures the high part is on the right and in another, the high part is on the left. The photographer went to the other side of the bridge to finish up the shots. Now, the boat comes in from the right side, so it should, if going all the way under, exit on the left. Which it appears to do, until you realize that that photographer went to the other side of the bridge, so the perspective is entirely different. The boat comes out on the left side now, which is the right side for those standing on the other side of the bridge and looking at the river. WHICH IS THE SIDE THAT IT CAME IN FROM. So YES, it did.

Look at the shadows cast by the bridge. They are going the same direction in all photos that show them.

The photographer just walked across the traffic lanes, and photographed the boat come out the other side.

The bridge superstructure appearing to shift sides is an effect of perspective.

The boat went completely under, knocking off the starboard funnel and deforming the rail as it scraped under the bridge.

Nope, look at the following:

1: The bridge is a lift bridge, and the lift section is UP - you can see the baricade in the span (5th picture), along with the sloped road - now LOOK at the 9th picture - the road and baricade are still there - the bridge looks like a single leaf bridge - most are

2: Look at picture 3 and picture 9 - in picture 9, you have the access stairway building, in picture 3, you can see all the way across the river, it's not there

3: Picture 12 - look at the downstream turbulance around each object in the water (Bridge piers, that stairway) - your sure not getting that on the upstream side of the bridge - look at the upstream photos

4:Look at photo 1 - there are no wires crossing upstream - look for the towers - now look at the last 5 or 6 photos - tower and wires - NOT the ones going to the bridge - the ones crossing the river

5:Release a set of barges in a river moving that fast, and they aren't going to stay upstream, they are going to keep moving - now the fact is, unless the barges stopped (and if they could, the tug could too), and the barge spead up to get in front of them, the barges went in front of the tug, which means under the bridge. The tug collects the barges at the end, on the side it ended up! So unless they anchored the barges, the tug speed up and rammed the bridge, came out the same side, and NOW had the power to resist the river to go get the barges, it went under

If it is an effect of perspective (thanks, Joe!), then I can accept that it went out on the opposite side. If the photographer went to the other side, then it definitely came out on the same side that it went in on.

There. Clarification.

Ah! the Wires!

Here's an image which may clear some things up. I took 
the image of the little girl on the bridge (towboat04.jpg) 
and used it as an anchor around which to build a panoramic 
view of the whole scene.

As you can see, I cut portions out of the other images and 
then spliced them onto the anchor by means of lining up the 
tree line.

Look at the overhead lines, which have been mentioned 
before. They start on the image just after the one with 
the girl (towboat05.jpg), but they must just be nonvisible 
in towboat04.jpg, because the tree line is otherwise 
identical.

Ahhh, the free time that comes with being laid-off.

Yes...the powerlines wires make it clear, and perspective=parallax, as I said before. All pix were taken from the same side of the river, with the current flowing from right to left.

Why the photog would suddenly decide to run across a drawbridge in the middle of an incident like this, I couldn't say. Sounds like an unsmart move, (doubly so if the bridge was opened; I don't think it was). KInd of like that guy who ran along the node line just before Galloping Gertie (the bridge in the K5 logo) fell apart.

IIRC the caption writer *said* the bridge was "closed", which I took to mean "lowered", that being the reason the whole mess (tow boat + barges) couldn't just steam right though, and was the reason the boat capsized..it was forced *under* the still-lowered drawbridge by the current. The barricades may have been to close the bridge to traffic for some reason other than to raise the draw. Perhaps it was being repaired, which might explain why it couldn't be raised.

Any super sleuths find out where this is? Deno...Bridge...anybody with the Army Corps of Engineers?

Okay. Who spread the link?

Just a bit of trivia: my web server's connection got overloaded because (get this) 178,260+ individual requests for that webpage. Now, the only place I mentioned it was here....

After moving the files, the problem (Tony knows what I'm talking about) is fixed (except the ISP now has us capped at 128K up). Anyway... Who told?

Griff · 02-22-2002, 01:09 PM

ooh oh
I showed it to my father-in-law forgetting he is a committed email spammer. I showed it to him on my machine but he coulda sent the link home when I wasn't lookin... a thousand pardons if I started the collapse of western civilization with a keystroke

Nah, 'sallgood now. Getting email was hell for a couple days though.

That could definitely start it, but one has to wonder how 178,260 individuals would get it just from that. Suppose that each person looked at it roughly 4 times with different IP addresses - probably an understatement. So we'll say that's 50,000 actual people that hit that link.

That's still a lot.

The ISP (i55.com) was SO hit by the requests on that line (which also, by the way, houses their MAIL SERVERS) that they capped us - no one at i55.com or their residential customers could get their email. All because of that little mirror I did and the one single link I made to it - right here on the Cellar. I didn't even email people about it.

As of last night, there was a request for the page coming in every 2 to 5 seconds - roughly 17,000 requests a day at that time. I moved the pictures and page and connectivity was almost immediately re-established with the server - I could get in just fine. So that was definitely the problem.

Anyway, it's no big deal. Just thought I'd share.

Wow, Griff, I bet you had NO idea you could single-handedly cause the /. effect on a server!

Such power ....

Kinda like bringing down the government by smokin pot... its just too easy.
