An Unexpected Honor After 34 Years as an ASME Member

A Modern Equivalent of “Beating Swords into Plowshares”

Every once in a while I write a blog related to my life before AFT. Today is one of those days. And I am going to talk about swords and plowshares.

What Do the New AFT Impulse 7 and Bordeaux, France Have in Common?

I think this is the third monthly blog article I have written this year from an airplane over the Atlantic Ocean. Truly I do not save my monthly blogs for airplanes. I am really busy most all the time these days. Being on an international flight means having a long, forced time disconnected from the Internet and more free time than normal to write....
