May I take the opportunity of invading this thread to ask a question which has long perplexed me?
Suppose that one were in an archipeligo and had laid on a heliecopter on pontoons to ferry divers quickely and comfortably from one inaccessible dive site to another. If no helicopter flight were to take place at an altitude greater than 1,000ft above the sea level, would such a venture be feasible in terms of divier safety?
