Neil Armstrong

The first man who stepped onto the Moon has passed away. We stopped building the Saturn V, threw away the Apollo infrastructure. We built the Shuttle and threw it away. We've had several iterations of replacements and they seem to go nowhere and probably will be thrown away. NASA is directionless.

Such a sad day in so, so, many ways.

Addendum (items will be added as I find them, if they are unique and interesting): Neil, Neil and Neal.
