U.S.S.R.'s Lunokhod 1 lunar rover returned to Luna 17 landing stage, completing one of planned experiments for Luna 17. Tass said vehicle "turned in its tracks about half a kilometer [about one third mile] from the landing area. For some time the old track showed clearly on the television screen and the controllers . . . used it for guidance. For the first time in the history of cosmonautics there was a solution to a practical navigation problem: The return of the self-propelled apparatus to a preplanned point at a preplanned time on the surface of a different celestial body." Vehicle had traveled 3173 m (10 410 ft) since it landed on moon's Sea of Rains Nov. 17, 1970. (SBD, 1/19/71, 68)
Ornithologists working with FAA had attached midget radios to migratory whistling swans to trace migration patterns and help avoid collisions with aircraft, New York Times reported. In joint project of Johns Hopkins Univ. and Queens Univ. in Kingston, Ontario, small aircraft pursued migrating flock between U.S. and Canada to monitor radios. FAA spokesman had said aircraft collisions with birds occurred "fairly frequently" though fatalities were "very rare." (Devlin, NYT, 1/17/71, 41)
