As an aerospace engineer, this still blows my mind! The SR-71 flew on the walls of my childhood bedroom, above plastic models of the same design. The Blackbird is still the sexiest machine ever created, to me!
With the advanced design tools we have today, I cannot fathom creating such a masterpiece with paper, graphite and a slide rule.
Thank you indeed Mr. Merryman, because there is no way I could do my job without your contributions to technology.
My TI-83 still never leaves arms reach.
