The SA-3 Saturn I lifts off on the rocket's third flight and second flight of Project Highwater, from Launch Complex 34, Cape Canaveral, Florida.
"This mission was the first time the Saturn I rocket was launched with a full load of propellant, carrying approximately 750,000 pounds (340,000 kg) of fuel."
"Project Highwater, authorized by NASA's Office of Space Sciences. The inert S-IV and S-V stages for these launches carried 109,000 liters, or 30,000 gallons, of ballast water for release in the upper atmosphere. This was used to study the effects on radio transmission and changes in local weather conditions. At an altitude of 150 km, explosive devices ruptured the S-IV and S-V tanks, and in five seconds, ground observers saw the formation of a huge ice cloud estimated to be several kilometers in diameter."
