Colonel Lansfield
Background
Lansfield is a colonel in the United States Space Exploration Wing. He is in charge of Lunar Base 1.
During the events of The Phantom Planet (1961) played by Richard Weber
On Lunar Base 1, Colonel Lansfield tells Lieutenant Cutler how incredible it is that two ships would be missing in less than a month and yet nothing was nearby. Cutler tells him Lunar Base 2 and 3 reported that a planetoid appeared and then quickly disappeared. The Communications Officer receives a message from General Gibson from Earth Headquarters for Lansfield. Gibson asks Lansfield what is going on and Lansfield tells him he doesn't know what is going on. Gibson then orders Lansfield to send Captain Frank Chapman out on a reconnaissance mission. Chapman walks into the room and Lansfield tells him he is to leave tomorrow for a reconnaissance mission. After Chapman leaves, the Communications Officer contacts Chapman and Lansfield asks if he sees anything. Chapman tells him he hasn't and Lansfield tells him to stay on course unless he finds something, in which case he is to report it at once. After some time with no communication, Cutler tells Lansfield there still hasn't been any communication with Chapman and Lansfield decides that if he doesn't hear anything back soon, he will send a search party out. The Radar Officer tells Lansfield that an unidentified object has appeared on screen. Lansfield then orders Captain Beecher and Lieutenant White to report and prepare to launch. After they find Pegasus IV, Beecher reports to Lunar Base 1 and tells them Chapman and Makonnen are gone and Lansfield orders him to fly in Pegasus IV while White flies their rocket.
