Not to beat a dead horse, but I don't believe the guy is holding on to
a "big handle to throw the switch", but is resting his hand on a
control box for the double-slip. He would need two levers (one for
each of the six points) and the it would have be much longer to provide
leverage to throw them. One other point; he wouldn't be sitting down
either; he'd constantly be jumping up. Just my opinion.
