Steve,
At some pressure you would have that problem -
definetly. Flotation material comes in many forms - and the cost increses as the
efficiency decays with depth. Wood might work nicely down to several hundered
meters - and i felt this would cover the needs for a psub. Since most psubers
make submarines for moderat depth - i must say that it would be most intresting
if someone considered what deep diving really takes. Is it remotly
posible
that a psub sometime lands next to the grand
staircase on the wreck of the RMS Titanic - I don´t know - but he would
need somthing stronger than dry pinewood for flotation. And yes - the
wooden decks of deap sea wrecks are not crushed. Bismarck´s planking are
quite intact. If pressure were to crush paintet wood - ( since the cells
cant flood fast ) it would likely be seen on deap sea wooden wrecks
?
Regards,
Peter
