Weather Balloons at Indian Springs Air Force Base.
"These captive, helium-filled 'Kytoon' balloons are used to obtain information concerning air pressure, temperature and humidity, as well as other meteorological data during the atomic test periods at the Nevada Proving Grounds. Sent aloft before each nuclear test, the balloons are hauled down minutes before the actual detonation occurs. Last minute weather information is thus relayed from the Indian Springs Air Force Base to the Atomic Energy Commission's Test Director at the control point. Such data is used to predict subsequent paths of radioactive clouds through the atmosphere."
