Miss Ealand's
"MICRO RADIO"


Miss Ealand's Micro Radio can be seen near the beginning of the UFO Episode: "Court Martial" [Timing: 03:15 > 03:35]. Commander Straker's secretary, Miss Ealand had evidently left her radio playing whilst she was away from her desk, or maybe she had even left for the day. Commander Straker is intrigued as he hears music whilst walking past her desk. He stops, picks up the radio and is clearly fascinated and intrigued by the miniature technical marvel.
