Just read a couple minutes ago... no one hurt apparently, but it did damage an aircraft. Few details.

Wow... Good to see that no one was hurt. This is one of those things that worry me about working the ramp....

Glad to hear no one was hurt, but what is the extent of the damage to the aircraft? An automated bridge collapsing onto a wing surely isn't good. Possible writeoff? Anyone know what kind of plane was involved?

I'm assuming it was a 737 or an Airbus, I think those are the only aircraft the bridge works with right now.

For those who haven't seen it, this is the bridge in question:

Aircraft was a 752... Either they were not using the rear jet bridge and it came crashing down, or the media has the wrong information and they were trying to deboard from 1L and 2L with 'traditional' double jet bridges. I have no idea which.

DewBridge.

Here are some pictures of the jet bridge:






These five jet bridges were added back in August and were completely financed by United.

Airport officials were not too fond of them and thus were not willing to take part in it.

Yes, but they aren't automated.

The ones UA has in DEN are automated and according to the article posted above, the sensor malfunctioned which is what caused the rear part of the jet bridge to drop onto the wing.

Yep, the 757 never uses dual jetways. Reason being that it is single aisle. So, people lining up through FC doesn't do anything to speed things along. The bridge does not have the capability to hook up to the rear door of the 757.

Ooohh... that no good. I don't know the engineering involved, but that sounds like the kind of collision that takes an aircraft out of service for a long while.

Anyone have any pics or know exactly what the extent of the damage is? It might not be worth it to repair a 757 if it's badly damaged - some of those UA 752s are pretty old IIRC.

Still, 757s are hard to come by these days. UA might have a hell of a time trying to find a replacement aircraft.

Oh, that doesn't look bad at all. But those pics are from a distance, so it may be worse than it looks. Definitely not a write-off though.

The wing looks fine to me. It probably has some minor scrapes, scratches, etc. here and there. The plane should be back in the air pretty soon. Nevertheless it still needs to be checked just to make sure. Hopefully there aren't any punctures or big dents.

That jet bridge doesn't look very safe to me. looks heavy and clunky.

I think these pictures are after the fact. I heard it did damage the wing pretty bad...

Anyway, I was not a fan of going to those jetways, not because of the automation, but because of the mechanics. The lack of structural support under the heavy extension just doesn't jive with me. I know the extension is anchored by the last pylon, but it just doesn't look right to me. Add a few months of moving those anchored supports around, and well, it ain't gettin' any stronger...
