I've read the Accident report. Something strange happened with the throttles. One engine was a runaway and the other gained some RPM. At the same time, his speed was dropping below stall speed. The aircraft itself behaved as expected in a low-speed stall. He didn't have enough control authority to correct the roll.
I agree about the driveshafts. being routed weird. Maybe in a tunnel, like cars and trucks, but not beside and around the pilot. Given the technology of the time, they STILL could have run a steel tunnel and some sort of safety rings, like race cars use to prevent drive shafts from dropping and pole-vaulting cars.
Personally, I don't see the need for 2 engines and 2 shafts, when there are gearboxes that will split and counter-rotate the props.
Still, overall, it was designed for more than double the speed of the racing airplanes of the day. Gotta give the designers that much credit.
