Great myth regarding the German precision but the diagrams could have used a little bit of German precision: the diagrams showed all three trenches with the same delta X but in reality the control would have needed a larger delta X in order to be the same length as the others since the other trenches also had some delta Y. However I believe that in actuality the trenches were the same lengths (just the diagrams were off).
Would like to have seen an air bag control for the Clown Balloon airbag myth.
