Apollo 12: Fifty years ago, a passionate scientist's keen eye led to the first pinpoint landing on the Moon:
...other than being struck by lightning twice within the first minute after it lifted off, [Apollo 12] had an uneventful trip to the Moon... When Mission Commander Pete Conrad stepped out onto the lunar surface, he saw Surveyor 3, about 200 meters away. Ewen Whitaker had gotten it right.
...the astronauts sent a personal note to Whitaker, thanking him for his contributions, and that became one of Ewen’s prized possessions, framed and hanging on the wall of his house.
