Of current interest: Electronic aspects of operation skyhook 60 flights

GIANT BALLOONS, with a volume of 10 million cubic feet, were launched from an aircraft carrier in the Caribbean carrying equipment designed to record very-high-energy cosmic rays. The project, sponsored by the National Science Foundation and the Office of Naval Research, received fleet support from the U. S. Navy, which named the launching operation “Skyhook 60.” The over-all scientific program is known as Project ICEF (International Co-operative Emulsion Flights) because about 25 universities and other research institutions representing every continent except Antarctica are participants.
