OOOPS! I meant heavy weight, of course!

A long time ago, PBS showed some Air Force films of an anti-personnel
gas bomb that was just a propane tank, a puncture device to spray
liquid propane into the air, and a timer that fired a little ignition
system with a Champion Spark Plug, which I found amusing.

The timer let the cloud of liquid gas evaporate and expand before
buzzing the spark plug to set it off. They tested it in
heavily-forested military land with a herd of sheep to see how it
worked. The sheep simply exploded at some amazing distance from the
blast. You could see the blast's shock wave expanding as the forest
trees near the blast were laid waste while trees further out were
simply waved really hard to and fro as it passed them. This test only
detonated ONE propane bomb....

Most impressive for such a simple device. The canister was about 100#
of propane. Wonder how big the shockwave would be from a whole LNG
carrier, say in a big harbor like Charleston or Norfolk.

How stupid we all are to let it dock.....


Propane is far more dangerous than LNG - its light weight means that it
will stay on the surface before igniting. A propane storage facility
was quietly removed from my area when it was realized that it was a
larger liability than the LNG.

Agreed (G 'cept for the "light weight" part).
I'm always amused at peoples perspectives ...... how many drive by gas
stations with big propane tanks for filling their RV's and barbecue
tanks and give it a second thought?
If you want to see what can happen if you have a total failure of an LNG
tank, look up "Cleveland Disaster, 1944".

Isn't LNG [liquid natural gas] a natural mix of butane, propane and a
sprinkling of higher -anes?

Brian Whatcott Altus OK

Every now and then there's a report about how much of the city would
be obliterated if she blew, but I've been told that the best guess is
that an explosion would not be too disastrous.


I used to work a lot of electronics contracts for US Navy back in the 70s
and 80s. At Norfolk Navy Base, directly next door to the destroyer docks,
there was ALWAYS a Soviet grain ship loading from the grain elevators to
take home to the latest failed 5-year plan.

The XO of the USS Adams caught me screwing off in my AMEX Systems coveralls
on his main deck one day and asked what I was thinking about watching the
Soviet ship. "I'm wondering where and how many nuclear weapons she has
hidden away in the voids in her bilge.", I said pointing out the Soviet
ship. "Sure would make a big dent in the Navy on the East Coast, wouldn't
it?", I continued. "Wonder what frequency they are monitoring where the
instructions will come to set it off?"

All the ships were in port that day. Big carriers, whole squadrons of
cruisers, destroyers, auxiliaries. We didn't learn a damned thing from
Pearl Harbor in '41. Stupid just letting the damned Soviets anywhere near
the entrance to the harbor!


I guess it's a natural reaction, to associate a big object of obvious
foreign national origin and high visibility, close to national assets
- with danger.

What people tend to worry about rather more these days, is the
suitcase, hand-carried most anywhere you would hate to be
exposed to explosions.

It's primarily Methane (at least 90%) ..... may also contain some ethane
and propane.
LNG and it's vapors, supposedly cannot explode in an unconfined environment.

So tell me ...... just how would you go about "blowing up" a supertanker
full of crude, or an LNG ship?

Easy. Use a weapon of mass destruction.

Light a match
