Excellent information Elon.

Going back in history, Smokey wrote about a special dyno oil pan he built that
was about three feet deep and had plastic sides. After only a few minits running
there would be a few inches of oil in the bottom and the rest would fill with 
foam.
Also one of the early Cosworth F-1 engines had a centrifical air-oil seperator 
and
a small roots pump to evacuate ait from the motor. The wrist pin problem was
addressed with oil jets directed at the pin/bottom of the piston.
Aireation takes time. The more passes through the engine, the more air. This 
isn't
nearly  the problem at the end of 1320 feet as it is at the end of 26,400 feet. 
In my
opinion, it's a major cause of wet sump engine failures at Bonneville.
