Does anyone still need a dead man's trigger on a suicide bomber's vest explained to them anymore?

I wouldn't think so. At least I can think of several occasions on shows like Law & Order when they said the bomber had a dead man's trigger without further explanation.

Whine - for the first time this weekend, I finally got to just sit down and relax. Of course, that is when a first class headache decided to set in. No fair.

I couldn't say I actually know what a dead man's trigger is, but I don't think it usually matters in context?

Thinking for a second, is it something where it detonates if the person falls down or something?

Is that -- if the suicide bomber is killed before he can detonate his bomb, it detonates anyway? (I hadn't heard the term before, but it seems self-explanatory.)

It's usually a spring-loaded, hand-held detonator--like a grenade after you pull the pin--that has to be held, or pressure maintained on the trigger, to prevent detonation. The bomber dies, the pressure is released, and boom.

It's designed to discourage people from shooting the bomber.

It's precisely what it appears to sound like, but it hadn't occurred to me that people wouldn't know, and would be deducing it from the sentence.

It's derived from the railway, where the trains were designed to stop if the engineer controlling them died, IIRC.

They have them for boats, too. There's a ring that slips over the ignition on one end of a cord, the other end clips onto the driver's clothing or life vest. If the driver goes overboard, the cord pulls the ignition. It acts as a kill-switch. There's one on my treadmill. I never use it, though. Perhaps I should?

Oh yeah! The dead man's brake, I think it was called.

Oh Theo, much ~ma to your family.
