...we spotted three stage tanks and a line that went into the next room
So are we back to a possible line/broken line again?

...we spotted three stage tanks and a line that went into the next room
Ayisha:So are we back to a possible line/broken line again?
H2Andy:well, this is just a guess, but since they didn't run a line in (none was found), this guy probably ran a line out trying to find his way to an exit
that's SOP if you get lost, at least in cave diving, not sure in wreck diving
but it doesn't quite make sense ... if he reached the stages, why didn't he use them?
Rick Murchison:Of course it is... but we're talkin' 'bout wrecks here, not caves. There may be some special circumstance - I reckon you could scooter in the O-boat hangar bay, for example - where thirds needs modification, but it's pretty rare. (a third of your penetration gas... that's a third of what you have after reserving your lost-gas deco gas etc).

Understand, but... Using gas to try to cover a fatally flawed plan (strobes instead of a contiuous guideline) still leaves you with a fatally flawed plan.scububa:Been away for awhile, so just getting back to this...
what I was getting at is that when doing a penetration (pick your favorite overhead) without a line and using strobes or something with as many more failure modes than a line, you might should plan much more conservatively...if you can't find your way out, you can't find your way out...cave, cavern, wreck, mine, or whatever I left out...so, wreck vs. cave seems moot...doing something that you (potentially) hadn't done before or that wasn't "proven" (i.e. technique exporation) would suggest a reason to use a more conservative plan. I believe that is the basis of cavern and basic cave mandating a rule of 1/6s for doubles. At that level, you haven't done any of it before.
In my mind, using strobes to navigate out would fall into that sort of thought process. As divers, I don't think we should be planning with a "this might work" but rather a "what's plan B?". Most of the progress of diving seems to involve that model. But, I still have a lot to learn and haven't dove in a tremendous amount of different envrionments. Heck, when I jump into salt water, all my spider senses are tingling...
tridacna:No more guessing.
Howard made it made to the stage tanks. He thought about taking them to his buddies. He decided against it because he was worried that they may make it back to the tanks and he would not be there. They all owed too much deco for a safe ascent without stops. Howard surfaced, alerted the boat and then dropped down to 20 feet to complete his deco. Kevin apparently found his way out but not Scott or John.
I believe that lessons have been learned from this incident. I went to all three memorial services; It was horrible. Let's let this die and not rehash every detail over and over.
IMHO:
Lesson 1. Dive a plan
Lesson 2. Use your own reel and lay the line. All divers carried reels. None used it.
Lesson 3. Do not use someone else's old line. Who knows?
Lesson 4. Bring stage tanks closer to you than you think that you need them.
Lesson 5. Overconfidence is a bigger killer than inexperience.
Anyone who knew them or was with their friends and family at the funerals would know that the last thing that they would want is for their errors to be discussed ad infinitum. Let's learn a lesson and move on.
RIP my friends. It won't be the same up here without you.
