''Blast through'' doesn't mean that it can't rip it off: we're talking about an explosion in a closed off area (the hatch would be thrown back on after inserting the grenade in ofc) against a piece of steel which is on hinges -- it's safe to assume that perhaps it wouldn't blast through but it can definetely blow it off it's hinges.

Fair enough, I left it up to interpetation in the IC. I didn't describe what happened to much. I hope others post soon now. :)
