This immediately discards like, everything you've said up until now, though. It matters if it explodes on the way up challenger style and irradiates half of the continent with a massive dirty bomb of nuclear waste. It's way more cost effective, efficient, and safer to just put it somewhere behind a big concrete block and then pay some guy to watch it 24/7, and make sure the big concrete block doesn't crack open or suffer from water infiltration or whatever.
