It's been thoroughly gone through and all. They have a dedicated guy for that. He does it all. Steam tractors, Piper Cubs, etc.. There was a guy like that out at the port when I worked there. My job was to lift him up on a forklift wherever he wanted to go. OSHA may not would have approved, but he damn sure got it done. He engineered the 40k forklift with with counter-weights made of steel plate we already had. Basically it was just big bolts with plates added on on the back. We pushed the limits.
