if he's in there, good for him. he ain't coming back out. he did a heck of a job.
How small is the last restriction, exactly? Does it require gear removal? The news reports said the rescue divers wouldn't venture beyond it. If he's actually in there, could he have removed his gear, went through it, and got lost or stuck beyond that point?
It's looking more and more like he's not in there, but just wondering. Thanks.
