John Glenn was a hero; was he a pioneer?
John Herschel Glenn passed away recently at age 95. He was the first American to orbit the Earth, on board Friendship 7 in February 1962, and before that, a much decorated war veteran, serving as a fighter pilot in both World War II and in Korea, finally retiring as a colonel in 1965. As if that wasn’t enough, after leaving NASA, he won a US Senate seat, representing his home state of Ohio, and served for 25 years.
