It was the first orbital flight around the Earth by an American. Glenn made three orbits over the course of nearly five hours, before safely splashing down in the Atlantic.
Just think: it was only seven and a half years after Glenn's flight that we were walking on the moon.
How come we can't do cool stuff like that anymore? I mean, we use to make it look so easy...
I met John Glenn on Halloween Night in 1988. He came to my high school to campaign for the incumbent congressman from our district. Wish I'd gotten a photo of he and I together, but I do still have his autograph.
Anyway, here's wishing John Glenn a very happy anniversary of his pioneering flight! And hey, he's still looking in good shape at 90! I bet he'd be up for a trip to the International Space Station (if his lovely wife of 70 years will let him :-)
