Throughout his career, he would celebrate that day as his anniversary day, his cherry tree day, and he would regularly read and reread the works of Verne and of Wells in order to renew his inspiration and his commitment over the decades of labor and effort that would be required to realize the first part of his dream: the flight of a liquid fuel rocket, which he finally achieved in 1926.
Durante toda su carrera, siempre celebraba ese día como su aniversario, como el día del cerezo, y leía y releía con frecuencia las historias de Verne y Wells para renovar su compromiso y su imaginación durante las décadas de trabajo y esfuerzo que demandó la concreción de la primera parte de su sueño: el vuelo de un cohete impulsado por combustible líquido. Consiguió esto en 1926.
