The closest I have come was a Boeing PT-17 Stearman; I received a certificate for the ride as a birthday present some years ago. Like the Waco, the big Boeing is an open-air biplane powered by a big, round (and L - O - U - D) engine. I believe the Waco (like the Buecker Jungmeister) has aerobatic capability; the Stearman I flew on did not. Nevertheless, riding in an open cockpit of a 50-year-old airplane was quite a thrill, an experience I have not forgotten.
The aeroplane has unveiled for us the true face of the earth. -Antoine de Saint-Exupery
