Ah wow. This is fascinating. The temps got up to 180C/356F when they expected 100C/212F. And then: > The unexpected decrease in density, the greater porosity, and the unexpectedly high temperatures caused the rock to behave somewhat like a plastic, making drilling nearly impossible.

Looks like a fun film too. ^^ https://www.youtube.com/watch?v=aO6gYI_LXBo https://www.youtube.com/watch?v=aO6gYI_LXBo
