Yes, you did. In fact my whole post about manpower being an issue was a direct reply to you, and you even wrote a relatively-lengthy reply to me in which you failed to adequately address my concern.
For some reason ‘manpower’ was left out of your list of reasons. I can’t speak for the mods, but I see it as one of the biggest and most obvious reasons.
I’m not against your idealism and optimism, but they must ultimately be grounded in hard reality. Trying to fly without the proper technology is a Greek tragedy waiting to happen.
