Alright so how about we build an air tight enclosure around a small part of the door, just big enough to get, say, a small drone through. A mechanical part of this enclosure would be saws or something to breech the door. Would probably want to draw a vacuum in the enclosure first just in case… maybe the enclosure could act as an airlock so researchers could access the drone for charging, upgrading, repairs, and whatnot?

I heard of this tomb when I was really young and ever since I’ve kinda used it as an engineering exercise in my head. Sometimes I draw things out for myself but this is the first time I’ve ever told anyone about it lol
