I saw the live broadcast of John F Kennedy's "Man on the Moon" speech and wasn't sure it could happen. I saw the live broadcast of "One small step for man" and believed that anything we set our minds to could happen. The Apollo project ignited the imaginations of millions of young people resulting in the marvelous technology we now have. What challenge can we give the young people of today to inspire their dreams?

Love the sound of the Saturn V at the start. I can't imagine what that thing sounded like in person. I was SO close to seeing a shuttle launch in 2009 in Florida, but it was delayed due to a weather warning. :( Wish I could have been in the US to see the first Falcon Heavy launch. That thing looked epic.

I was sitting here being mildly amused that all of your ancient HP tech you are using to test this thing is probably 10 to 15 years newer than the thing itself, and can probably read to 3 to 6 more digits than the equipment they used when they built and qualified this equipment. (I have nothing against ancient HP tech, I have a lot of it myself.)

These tools are worth every penny though. Absolutely dependable. I’ve been using the same style of a tool with Hirschmann connector pins - zero field failures. These four-indent crimps form gasless joints and flow the contact and wire metals together. For an extra 1000+ year reliability use Teflon insulated wires and crimp in a dry Nitrogen laminar hood. It’s basically expected to last millenia then, without any wire-to-contact degradation.
