I have no doubt I am a very lucky person. Although I do not have an education in any science, I was able to spend approximately two decades working on the Space Shuttle Main Engine (SSME) program at Rocketdyne (through four major aerospace corporations). I spent a lot of time working with some of the brightest rocket scientists (for realz) as well as world-class engineers and scientists in literally dozens of disciplines.
Since my retirement from (what was then) Pratt & Whitney Rocketdyne, I have worked intermittently with Quantellia, LLC, an artificial intelligence / machine learning software development firm. Needles to say, I have no formal education in any computer field, with the exception of two Visual Basic classes I took at a nearby Junior College. I was introduced to one of the co-founders of Quantellia shortly after my retirement. She showed me a tool they had been developing called “World Modeler”. It was the most exciting thing I’d seen in a long time, and I was especially impressed with how it brought a highly systemic approach to modeling and forecasting in complex situations. I ended up writing several papers and a bunch of case studies for them.
In 2015 I returned to work at what was then Aerojet Rocketdyne (still is, for now) where I worked on a small rocket engine program for a little over two years. After leaving, I started doing some selling for Quantellia and, beginning in March of 2018, I became the company’s Business Manager, a position I’m still working at.
Last year we held a summit, in conjunction with SAP Global Services, at their Labs in Palo Alto. It was called the “Responsible AI/DI Summit.” In this context AI stands for “Artificial Intelligence” and DI stands for “Decision Intelligence.” One of the main purposes of the summit was to discuss how we can develop artificial and decision intelligence such that we concentrate on using them to solve humanity’s most “wicked” problems, rather than merely work at developing apps, the main purpose of which is to make money for the developers, investors, and entrepreneurs involved in the business.
Below are some of the folks who worked on the Summit, including me (the long-haired guy in the middle of the back row). Also, here’s a link to this year’s second Summit – Responsible AI/DI Summit 2019, as well as a link to the RAIDI Blog.
As I learn more about machine learning, artificial intelligence, and decision intelligence, I will work at sharing my knowledge and understanding of these tools, and the issues they raise. I know the people I’m working with are dedicated to serving humanity, not merely milking it for profit. That pleases me and I hope we’ll be able to prove we’re doing the right things to ensure such service continues to exist and grow.

I must admit to being a little mystified that NASA hasn’t chosen to fly over and salute Rocketdyne today. Every main engine that powered every Shuttle flight into orbit was designed, manufactured, and assembled primarily at the Canoga Avenue campus. I know they couldn’t fly over every place where components were made in the country, but they’re flying over the freaking Hollywood sign and Universal Studios! Rocketdyne’s campus is just a few miles to the Northwest of those locations. How hard would it have been?
I have often lamented the fact that Rocketdyne never saw fit to advertise itself much. Whenever there was a launch of an Atlas or Delta vehicle, the vehicle manufacturers and integrators always had their names and logos prominently displayed. I am willing to bet very few people in this country even recognize the name Rocketdyne. Do they know every American Astronaut (other than those who’ve flown on Russian missions) was lifted into space by a Rocketdyne engine? I doubt it.
Mercury, Gemini, Apollo. All those flights were powered by Rocketdyne engines. The Lunar Excursion Module (LEM) was powered off the Moon’s surface by a Rocketdyne engine. The Space Shuttle Orbiters would never have made it to LEO were it not for the Space Shuttle Main Engines. The SRBs (Solid Rocket Boosters – or Motors, SRMs) only burned for 126 seconds before separation from the vehicle stack. The Main Engines continued burning for approximately six more minutes, depending on the mission. The SSME was – and still is, as far as I’m aware – the only reusable and fully throttleable rocket engine ever designed and flown.
Anyway, today marks what for me is a very sad day. It should be sad for all of us, IMO. This is the final flight (albeit strapped to the back of the SCA, a specially modified 747) of the last of the Orbiter Vehicles that served us for well over two decades and, unfortunately, we currently have nothing to replace it. The ISS is still on orbit, but we now have to hitchhike there aboard Russian rockets. There’s really no way to tell how long it will be before we return to space.
It also reminds me that I was put out to pasture, though nobody’s suggested ensconcing me in a museum 🙂 I didn’t realize how much retirement would affect me. I’ve enjoyed having time to be with my children, who are eight and eleven. I’ve also enjoyed working at building a modest service business supplying social media marketing for small businesses. However, in this economy that has turned out to not be a very useful business model and, once again, I find I must reinvent myself. Today I’ve decided to wallow a bit in my grief. Grief for the symbolic end of the Shuttle program, on which I labored for over two decades and grief for the symbolic end of my usefulness as a human being, which is what retirement sometimes feels like.

One more thing. In my opinion Rocketdyne deserves better. I know people whose entire lives were dedicated to the space program. They worked tirelessly; lived and breathed the concept of space travel and exploration. And those engines played a major role in putting Endeavour (OV-105) on orbit. Just sayin’.
I retired nearly 13 years ago, though I've continued to work during most of the time since then. I'm hoping to return to work on the RS-25 rocket engine program (formerly the SSME) which will power our return to the moon. Mostly I'm just cruising, making the most of what time I have remaining.
Although my time is nearly up, I still care deeply about the kind of world I'll be leaving to those who follow me and, to that end, I am devoted to seeing the forces of repression and authoritarianism are at least held at bay, if not crushed out of existence.
I write about things that interest me and, as an eclectic soul, my interests run the gamut from science to spirituality, governance to economics, art and engineering. I'm hopeful one day my children will read what I've left behind.
