I never understood why we never pumped acetylene down those holes. It would have been messy.

Wondered that too until I saw a diagram of an typical Cong tunnel system.
Much like the U shaped water trap in the waste water system in your plumbing which keeps septic tank gases from bubbling back up the pipes, the Cong dug water traps to prevent our troops from attempting the same.
Not a Viet Nam vet but that's my understanding of it...
