From the Wright brothers’ first flight in Kitty Hawk, until Neil Armstrong’s first footstep on the moon, it had been just over 65 and a half years. At the time of writing, we have just over 16 and a half years until 2035-02-28. At that point, it will have been even longer than that since Neil Armstrong stepped foot on the moon. I hope that since then we will have been back to the moon in earnest.
