Rhett analyzes a loop-the-loop; This is the same stunt (or is basically identical to the same stunt) I blogged about in May because the newspaper story summarizing it was so awful. But Rhett has graphs and charts and twenty seven eight-by-ten color glossy photographs with circles and arrows and a paragraph on the back of each one explaining what each one is. So check it out.

And Matt has the same topic but with half as many wheels, in Diavolo riding the loop on a bicycle.
