Dear Neil Armstrong,
While this is an open letter to you, you likely won’t respond because you are dead. None the less I wanted to express how mind-blowingly awesome you are. When your Gemini craft docked with the Agena target and spun out of control, did you panic? No, you performed calmly as trained. When your lunar trainer went out of control and almost killed you, did you panic? No, you bit your tongue a little and calmly ejected. When the lunar module had 40 seconds of fuel left and 1202 alarms are going off, did you panic? No, you landed the LM calm as a cucumber. There are Zen monks whose brains fluster in comparison. You are an inspiration to thinking things through and practicing until you cannot get it wrong.
Per aspera ad astra,
P.S. It is because of you and the Apollo flight controllers that I learned how to use a slide rule.
