I think the best moment in the Aviation History is the 1969 Landing on the moon by the Apollo 11, because it represents the summit of the aviation and at the same time, what we (the human beings) can reach if we just propose it.

Has to be Apollo 11, shame the question is about aviation. Maybe you could pick that certain flight in Wright field but I think all of us in aerospace know that Apollo 11 and its subsequent follow-on missions, is the summit of human technical achievement. Hopefully one day we will return.

Has to be Apollo 11: the point of arrival of a lifetime dream for me and, I believe, for all who witnessed it during that sleepless night.
Shall we find a way to continue?
