Just a personal point of view.
I’ve been in many, many small caves like this. Very, very few, if any, for that matter, have I thought along the lines of “no way are you ever gonna get a body outa here”. A seriously injured person without making it worse ? Oh yeah. A body ? Can do, maybe.
Thats not to say that 20 hours into trying with an army of cavers working round the clock and noting that we have only gotten 1 percent of the way to the entrance at which point I wouldn’t go “this aint gonna work”. But this can’t do attitude regarding body recovery is bothersome to me.
I am still of the opinion that this a bad idea. The body is gonna be there. The cave will NOW be even MORE infamous because a body is STILL there rather than “just” somebody died there. So, the legend will take much longer to fade. Every few years there will be yet another newspaper article when the news is slow. And now all the flashlight cavers will still be drawn, if not more drawn to that area, because of this legend. They will just focus their efforts on the other surrounding caves in the area. And I’d bet dollars to doughnuts that THOSE caves are about the same danger wise as the one now sealed. That just makes matters worse. And I’d still wager that down the line the family will wish the body was recovered. And the blasting of the passage leading to the body will just make it ACTUALLY dangerous to recover the body once someone decides to try to do it. A small passage is very safe if you fit and know your limits. A passage blasted shut is way more dangerous and uncertain.
