Rest in Peace. Enjoy July (see his story above)

Great articles, video, and philosophy.

By coincidence, a friend of mine mentioned him the day before I saw this post. My friend was a Crew Chief with him and said he was highly respected.

Now I can see why.

Aviation is an awfully small world.

Here's to you, Muck.
