Went to see 'Into the Blue' last night, have to admit to really
enjoying the film.

Would like to dive the Bahamas - but not to sure about breathing direct
from a cylinder with no 1st stage !

If anybody else sees the file, can you explain why the plane exploded
at the end ? good effects but don't understand why a scuba cylinder
would do that.

Saw it a few days back. Entertaining (sometimes) and reasonable diving - at
least no-one referred to "oxygen bottles". However they really need to look
at their gauges more often, and their lifting techniques leave lots to be
desired.

I too would not relish the thought of breathing straight off a cylinder
unless I had to. Knowing he was going to take the cylinder into the fuselage
of the submerged 'plane hoping the missing diver was OK in an air pocket,
would you not swim on the surface until directly over the plane and THEN
duck under, rather than get to the bottom about 50 - 100m away from the
'plane and then swim towards it?

Then the system of clearing sand from an archaeological site - blast it away
with the wash of your props (no viz for days!) or suck away gently instead,
depositing the silt some distance away down current??

The Mel Fisher museum in Key West showed that, maybe for reasons of
economy, they used ducted propwash from the boat to clear the artifact site.

Maybe it was just cheaper and easier.

Oh indeed it would be, and my comment as to the silt was tongue in cheek -
in inherently clear water it would not take long for the viz to return. OTOH
we are reminded by archaeologists that items of no intrinsic value may be of
great archaeological value, and part of their worth is in knowing their
position relative to other items. When you have a controlled suction pipe
clearing an area grid square at a time and the collected suctate (is that a
word?) filtered you can indeed piece things together. Blowing 1000bhp of
power towards your site with ducted prop wash seems almost certain to make
this task impossible - unless of course you care not a fig for it and are
really a treasure hunter, after lumps of gold and similar.
