Snipping the wires on a time bomb

You’re my kind of evil.

At Edwards AFB I was talking to some security types about the Barrett .50 on their HMMWV. They said the rifle was used to explode bombs/unexploded ordnance from a safe distance.

Does anyone remember the multiple antitamper devices in Special Bulletin?

Can you provide your source for this?

I don’t remember it happening in the way you state, I thought they became fairly adept at bomb disposal. Certainly we read of casualties at the time but especially with the advent of the remote controlled robots it was comparatively rare to read about them.
I just can’t remember this “cycle” of events happening.

This article gives a brief history of EOD

In ‘The Fourth Protocol’:

a top KGB operative has a plan to detonate a nuclear device next to a US nuclear airbase in the UK, and blame the US.

A male operative has collected the components and been told he will have two hours on the timer after setting the bomb to get away.
The KGB villain sends a female technician to assemble the bomb.
So as to leave no evidence, the female is told to set the bomb to explode immediately after arming.
The male (who doesn’t know the timings have been changed) is told to kill the female as soon as the bomb is assembled.

Typical chess player plot!

Real bomb disposal teams blow the thing in place as the first option. If that’s not possible, or too dangerous to the surroundings, they remove it to a safe place and blow it up. Only as a very last resort do they try to disassemble it.

When were you 12? This was exactly what they did in “Lethal Weapon 2”, when Murtaugh found the bomb behind the toilet he was sitting on, with of course a pressure sensor set to detonate when weight was removed from the toilet seat. They put a styrofoam case around the bomb, filled it with liquid nitrogen, then Riggs pulled Murtaugh into the bathtub. The bomb did go off a few seconds later- the liquid nitrogen delayed the blast somehow. I don’t remember enough semiconductor physics to know how realistic that is.

I certainly remember that MFTV movie. I was disappointed with all the disclaimers saying it wasn’t real. Dammit, I wanna see mass panic!

One of the Die Hard movies (I think) had a bomb in a school whereby two chemicals would mix and cause an explosion. They were both visible in large, transparent tanks. Rather than defuse the thing at the last minute, couldn’t the simply have drained one of the tanks?

Well, I was 12 substantially before Lethal Weapon I.

What if there was a fuse set to a sensor that monitored the pressure in the tanks?

What if chemical A was acid glue and chemical B was Hitler? What then?

Link to earlier, highly entertaining thread on life-or-death hypotheticals.

Natch, I got before I even got to the link…

Oh for god sakes! Don’t cut ANY wires, just unplug the the damn BATTERY!

It may have a capacitor somewhere that discharges on loss of current. Kaboom!

Oh, the ol’ capacitor discharge trick. (heh, heh) Forgot about that!---- Dammit.

That’s the second time I’ve fallen for that this week!

Too funny!

If I remember the movie correctly, they did get a bang anyway, but somehow everyone was miraculously spared the plutonium contamination.

I hated that movie. Where’d the frakking missile crate disappear to?

The British used it to defuse booby trapped German bombs during WWII, or at least they did in “Danger! UXB”.

That would be the third movie, Die Hard With A Vengeance, and the bomb of which you speak was worked on by what I consider to be the most heroic character in the movie. I don’t remember if they even gave him a name, but he’s a balding, pudgy bomb squad member.

Let’s go back there, shall we: the building has been evacuated with about 1:30 left on the timer, and the bomb squad tech packs up and starts to leave. Then, he hears on his radio that kids have been spotted in one of the rooms upstairs. “There are still kids in the building?” He pauses, then sets his tools down and turns back to the bomb. Calmly, he says, “I’m staying.” And, knowing that he’ll probably die very soon, he resumes work on the bomb.

THAT is bravery that should bring tears to your eyes. He’s the unsung hero of the movie.
