Yep, this plays out exactly as you’d expect it to.
At first it looks like they’ve done this before. They actually manage to get this giant piece of machinery halfway onto a tiny leaking dinghy. At least they nearly do!
Seriously, how could anyone think this is a good idea??
Then, it all goes wrong. Surprisingly, this ancient sinking boat isn’t made to carry a several ton excavator, and starts to capsize. Then, the excavator slides off and manages to take one of the natives out and wildly make it’s way to Davy Jones’s locker.
What an expensive disaster!
They’re going to need 2 more excavators and 2 more leaky boats to get that out of the ocean floor!
