Taken from an altitude of 450 miles (720 km), the pictures of cloud cover confirmed the spiral pattern of winds in a storm.[3]

As rumors spread that the Project had picked up signs of intelligent life, Drake was forced to say that he had no comment. The source was later traced to an airplane.[19]

On May 1, a U-2 plane flown by Francis Gary Powers would be struck down.[23]
- A fisherman in Masan, South Korea, discovered the mutilated body of Kim Chu Yol, a high school student who had been killed during March protests against the fraudulent presidential election.

- East Germany's Communist SED completed "Socialist Spring in the Countryside" ("Socialistische Frühling in der Land") its collective farming project, to finish the creation of the Landwirtschaftliche Produktionsgenossenschaft (agricultural production cooperative).
