Get a little rare earth magnet from Radioshack (2 in a blister pack) They are very skinny and you can use in on the inside of the case . Works great, been using it that way all week! I used a little black tape but I might as well epoxy it in place now that I have verified positioning and operation.

I think avoiding drama is a much wiser course of action in an airport these days...

Yeah, aflegg has a point. An element of drama might lead you to a questioning cell kept in an unknown location for an undetermined amount of time and then it's just not funny anymore.

Luna, thanks for the suggestion on the magnets from Radio Shack! Those probably don't scream "magnet" quite as much, especially if it's on the inside.

these magnets are very very small.i even thought of making a small cut and implanting it an clean it up with a leather repair kit.

I agree, I never dramatically withdraw my 770 from it's bag in the security line. That is best done whilst waiting for the flight after the security screen.

...however, whatever you do, never say, "Damn thing bombed again!" anywhere at the airport.

I wouldn't use the word "crash", either.

What's needed is a case that has the magnet mounted in a slide switch, so that the user can enable/disable sleep as he chooses. Only thing to watch out for is sliding the magnet to an area where it can damage components, especially the screen or worse, memory.
