Is it used to work on aircraft?


Yes, amongst other things.

Yes, a little snow can make for good train spotting. Picture taken on OSR spur line near Tillsonburg, about an hour from my house, in January 2014.

You could probably pick your teeth with it, but that is not its intended use.

"Electronics" is an interesting question. The device this is used on is not, itself, electronic, and does not need electronics to be useful, but it may be part of an electronic system. Or it may not. That's your clue for today.

Not THE Doctor. (you know Who.)

But, if you use a broad definition of doctor, the person using is sorta kinda a doctor.

Metal, but not your usual screwdriver metal.

Time for another clue. It looks like a screwdriver, and the things that get turned have threads, but they are not screws (in the sense that screws hold things together).

braking screws loose


Nope. Time for a hint: when I used to use one of these it came with a short lanyard on the handle, because you could really upset certain people by dropping it while using it.

Sonic screwdriver!


Half right. Still need its special properties, and its special purpose.

Not a punch.
Not hardened.
Don't know about number on the end.

OK, we all know what this looks like. But it has special properties, and is used for a special purpose. I need both for the win.

Is that an official win?

Hooks up to an air wrench, to spread springs.

You're right Richard. There is a HUGE debate going on in Canada about doctors (especially surgeons) being required to use check lists by hospital management. Quite a few doctors argue that this somehow cheapens their careers. The fact that it occasionally saves lives appears to be of secondary importance to them.

I run into this mentality quite regularly when investigating machinery accidents. I've come to call these people "too cool for rules". I often hose their remains out of the works before starting my investigation.

(Feel free to move this post to Politics if needed. I never go there any more.)

As a big fan of efficiency, I like to say sextuple-u.

Very interesting story David. In flight test we call this "learning to ignore what doesn't kill you right away". Humans are just too flexible, they will quickly adapt to anything that doesn't offer an immediate dissuader. You skip check lists, you ignore buzzers and lights, and if you are still alive it is so much easier to repeat the action the next time. The most dangerous part on any aircraft is the sloppy link between the control stick and the throttle.

The automation and drone crowds, BTW, supports this theory 100%. Computers don't have this problem.

Would a vet use them?

The flanges may contact the rail when going around a corner, that's what produces the squealing noise you sometimes hear. In order to derail a car with a lateral load you need to lift the wheel enough that the flange rides over the rail. That requires a lot of energy. I'm told that a heavy car on a really tight curve will often grind to a stop before derailing. The main operational problem with curves is the extra drag produced, not derailing. As a previous post said, tight curves plus a slope can be especially painful.
