Project da Vinci-oft-delayed manned-atmospheric-research balloon flight-was terminated after one third of its projected 36-hr duration, because of threatening weather. The joint project of the Atomic Energy Commission, National Geographic Society, and the Army's Atmospheric Sciences Laboratory was intended primarily to investigate atmospheric behavior at 1200-4300 m, where less scientific research had been done than at very high and very low altitudes. Floating free and staying with a single parcel of air as long as possible, the four crewmen studied atmospheric behavior over mountains, plains, forests, and cities. They had hoped to travel in their 21-m helium balloon from the launch site at Las Cruces, N. Mex., to a landing near Lubbock, Tex. The project safety officer terminated the flight over Wagon Mound, N. Mex., but not before enough data had been gathered to plan future flights.
