I'd like to see that. Does it include clearing a 15 meter obstacle? My guess is that it involves a stiff headwind and, holding the brakes until it shakes like a wet dog.

People like me who collect ancient motor scooters often joke about improving performance by losing weight. That might work for pilots, too.

I lost 35 pounds once and sure enough, it improved speed and hill climbing ability of my older scooters. But I think the improved aerodynamics of a skinny rider helped as much as reduced load.
