Oh I see it's us on the outside that are not ready as the bunker door closes.

Not a problem. Call someone with a welding truck...

Call a Vet that had time in the sand box and he will show you how to make a giant can opener. Also cooks the meat inside at the same time.

A cheap cutting torch outfit on a tiny, cheap trailer will do it, or a mini cutting torch outfit. The hardware is cheap at Harbor Freight. There are also plasma cutters, air arcs, etc. A super cheap air arc setup can be made at home with a cheap arc welder and air compressor. There are also cutoff wheels for cheap grinders. Or one could simply build a giant bonfire over a bunker for a few hours to allow much more time to figure out how to get in later.
