October 23 Friday – Joe Twichell wrote a short note, clipping enclosed “Aerial Navigation”: “Don’t you remember how one of us said, when we last walked to the Tower, speaking of aerial navigation, that the problem was bound to be solved sometime, because it was never given up, but there were always men at work on it. / The sight of the enclosed recalled the remark” [MTP]. Note: Steering a balloon had always been a challenge.
