@roger,
Speaking of design, Ive been following that kerfuffle about the speed skaters uniforms with the "flap" that apparently acts like a big pizza box lid on the skaters backs. Is the flap system slowing our kids down?
I have an ad from BF Goodrich from a 1944 TIME magazine. The ad was for airliner tyres that have these little "Flaps" that catch the wind and make the tires "auto-rotate so that they are spinning as the plane lands.
SO, flaps DO affect the aerodynamics of any surface. I wonder whether they'll remove the suits with the forward facing and replace em for the final races
