I like the example of Kittyhawk to the moon - 66 years. I realize they are not commensurate, since rockets and balloons existed long before aircraft, and the Wright Flyer 1 is not really in the ancestral lineage of Apollo spacecraft. Those 67 years are still impressively short, even though the advances were mainly due to wars (hot and Cold).
