Thanks.  I forgot about the Cleveland
incident, but Cleveland incident happen
in 1944.  It was not a LNG tanker accident,
but a storage tank not built to specification
due to war effort and shortage of metal.
The new storage tank was not air tight, so
the resultant LNG mixed into the sewage
pipes and exploded killing hundred plus people.
LNG tanks build with 9% nickel has never
display a crack in 35 years of history.
This example was not built to 1941 US gov't
code for proper storage tank.  Of course,
accidents will occur if people are not
building according to regulations.

Talking about accidents in US.  There are
at least 2 other accidents involving deaths.
None of them involve tanker explosions.

As for Algeria's accident, that didn't cause
a nuclear like explosion.  This accident
results in damage similar to refinery plants.
Those things explode, too.  None of these
severly damage towns, etc.

The Cleveland incident is the worse one.
Hopefully, today's regulators and inspectos
will do a better job.

FYI: I am not an advocate of LNG.  I was
just playing devil's advocate.
