Gemini 4, the second crewed and first long-duration mission in the Gemini program, was launched from complex 19 at Cape Kennedy at 11:16 a.m. Command pilot Astronaut James A. McDivitt and pilot Astronaut Edward H. White II were the crew. At 3:45 p.m., when the craft was making its third orbit and passing at an altitude of above the southern United States, White, using a hand-held maneuvering gun, became the first U.S. astronaut (and only the second person, after Soviet cosmonaut Alexei Leonov had ventured outside Voskhod 2 on March 18) to walk in space. White stayed outside the capsule for 20 minutes as the ship moved at over the nation. Gemini 4 was the first mission to be controlled from the mission control center in Houston.

June 4, 1965 (Friday) Duane Earl Pope, a 22-year-old man who had graduated from McPherson College only a week earlier, committed what was called "the modern era's bloodiest bank robbery", murdering three people and critically wounding another. Pope, a resident of Salina, Kansas, drove to Big Springs, Nebraska, and walked into the Farmers State Bank at noon. There were no customers in the bank, but one of the four employees, a teller, pressed the button for the bank alarm. Pope then ordered the bank president, the teller, a bookkeeper, and another employee to lie face down on the floor, then shot all four in the back before escaping with $1,500. After a nationwide search that lasted a week, Pope called police in Kansas City, Missouri, and surrendered because he was "tired of running".
