I couldn't (respectfully) disagree more. He has inspired a generation of us, myself included.

My grandmother used to lead the Indianapolis Aero Club and somehow managed to get him as a speaker. My parents made the 2ish hour drive up just for me to hear one of my heros, Col John Glenn, talk for ~30 minutes (I was maybe 12-13 at the time?). While I did not ultimately achieve my dream of being an astronaut like him, I did however find my way into aerospace engineering and engineering in general as a result. He really inspired me on to greatness by being so down to earth and matter of fact.

And now I'll say something a bit controversial. The world needs more people like him, and less people like Zuckerberg. While building the next $web_thing or unicorn startup is cool, inspiring an entire generation is a whole lot cooler. Rest in peace John!

Black bars are essentially free; I never got the reason to ration them. While Glenn may not have been a part of the hacker community, he's an international icon of science, technology, and space exploration. I would guess a nontrivial number of people here have been positively influenced by John Glenn, and I'm sure every single person here has at least heard of him. I believe a black bar would be appropriate, as this is the only opportunity that we have to honor his passing.

People like John Glenn are the reason why I became infatuated with the space program and STEM. He showed the heights humanity could reach by using science and knowledge to become masters of our own destiny instead of victims of nature and fate. Before personal computers, before the Internet, before cellphones, humans landed on the moon & live streamed it to 600 million people. I feel the same way for artists like William Gibson and Neal Stephenson. It's become fashionable for many to deride the value of a non-STEM education. But if it weren't for them and their creation of the cyberpunk ethos and genre, I'd most likely be working at a bank or a hedge fund in a decidely non-technical role.

I also highly commend and greatly respect him for his efforts in nuclear non-proliferation. I imagine when you've seen earth from the view he had, you can't help seeing how small our differences actually are. That said, he wasn't perfect. His testimony in favor of excluding women from the astronaut program kept them from going on a mission until the 80's. To his credit, by the 1970's he had changed his mind and began supporting a female astronaut (Judith Resnick...interestingly she was recruited into the program by none than Lt. Uhura/Nichelle Nichols ) in her endeavors to join the astronaut program. Ultimately and unfortunately, she was a member of the ill-fated Challenger crew. Glenn gave a touching and inspirational speech at her memorial service that is worth reading: https://www.nasa.gov/centers/glenn/about/memorial.html

Off topic rant: As I hear this news, I'm reminded of the whole Buzz Aldrin dustup. While I'm no advocate of violence, I was inspired when he decked that looney conspiracy theorist who claimed the moon landings were faked. Despite the fact that you can literally shine lasers on the pieces of spacecraft left on the Moon and see the reflections, there are still those forces of ignorance who refuse to accept reality even as it stares them right in the eye. Most people in his position and especially at his age would simply try to avoid that confrontation and be content to let charlatans spread their destructive, nonsensical fictions. John Glenn was not that man. For some reason, that incident is what truly sticks out in my mind about him and I always associate him with this image: http://www.themarysue.com/wp-content/uploads/2016/05/3779149.... It's probably because I associate him with being the last of a dying breed, a modern hero in an increasingly cynical, post-modern society.
