The American flag was designed by a high school student

It started as a school project for Bob Heft’s junior-year history class, and it only earned a B- in 1958. His design had 50 stars even though Alaska and Hawaii weren’t states yet. Heft figured the two would earn statehood soon and showed the government his design. After President Dwight D. Eisenhower called to say his design was approved, Heft’s teacher changed his grade to an A.
