- WWII Role: The camp was reopened during World War II to train another generation of soldiers.
- Cultural Note: The famed “Yip Yip Yaphank” musical revue, written and performed by Irving Berlin while serving at Camp Upton, boosted morale and raised funds for the war effort.
- Today: After the wars, the site was converted into Brookhaven National Laboratory, one of the country’s leading scientific research centers, focusing on nuclear physics, energy, and medical breakthroughs.
Aviation History on Long Island
Charles Lindbergh’s 1927 Flight
- Location: Roosevelt Field, Garden City.
- Event: On May 20, 1927, Charles Lindbergh took off in the Spirit of St. Louis on the first solo nonstop flight across the Atlantic Ocean, landing in Paris 33 hours later.
