Last night, while making fun of Yahoo Answers, I ran across someone considering "getting their Monroe pierced". You know -- an ear piercing pierces your ear, a navel piercing pierces your navel, so a Monroe piercing must pierce your... Monroe.

Today, on the bus, someone tried to open the rear doors in front of an icy snowbank. The doors are hydraulically-assisted (or maybe pneumatically, but anyhow, pressure-assisted!) so when you push on the handle the door opens for you. They got halfway open and hit the snowbank, but they were still pressurized so you couldn't pull them shut.

The driver took care of this -- and in retrospect I've seen this before but I didn't know what was going on -- by shutting down the bus, waiting for the doors to close, and starting the bus again. That's one hell of a failure mode.

Is that not the very same 'failure mode' that nearly all PC users take advantage of?

I think mendel was referring to the fact that it was possible for a door to get stuck in a half-open position that it was impossible to get out of short of "rebooting" the bus as the failure mode -- that is, the half-open-but-can't-close-it state was the failure mode.

If I understand you correctly, you interpreted the "rebooting" procedure as the "failure mode". (At least, I don't know of any PC users that take advantage of a situation where windows open half-way and can then neither be opened fully nor closed...)

Already I am out of my depth; I retract my statement and retreat to Wordpress.

Yeah, pne has it -- I mean that it's unfortunate that you can get a bus door in a state that the only way to close the door is to shut down the whole bus.

(Restarting a bus isn't always easy -- the first time I saw this, the bus took probably five tries to restart -- and there's an interlock that prevents you from moving a bus with an opened back door so you can't even pull forward to let the door open all the way.)

Axe, maybe, or sledgehammer. With all the freezing and thawing it's all ice. But replace "snowbank" with "curb" and the door not having an override switch is still just as silly!

Maybe there is an override, but the bus driver is/was to lazy to get up and use it?

Driver's being lazy; there's a pressure relief valve behind a hatch above or near the door, I've seen Pittsburgh Port Authority drivers use it.
