I have some 5000 psi epoxy that they should have had along with a roll of gorilla tape in the tool box.. never know when you are going to need it.
They would have needed 6x6 timbers to support that plastic tube when it started to Crack. I’m thinking they may have seen a mist and then heard a huge boom and then nothing.... they were crushed to liverwurst consistency. I think I’m done. Former usn SS. Don’t like thinking about it.
