Terry Liittschwager's Officially Unofficial, Rarely Visited,

Curiously Chaotic Website

Welcome to my website. It wasn't designed with the public in mind, but feel free to browse whomever you are. I set up the domain in February 2010 for FTP purposes for DOS software I originally wrote in 1988 and that was used through the years at three airlines for Boeing 727, 747, and 767 aircraft, Douglas DC-9 and DC-10 aircraft, and Lockheed L-1011 aircraft. The last regular usage of the program stopped in 2016, so it had a 28 year life span. That's pretty good, if I do say so myself, for an old DOS program. For personal historical purposes, I've left some information about that program in the AVIATION > AIRCRAFT W&B > DOS W&B LINKS reachable in the navigation panel

In 2011 I decided I wanted to learn Javascript. A rewrite of that old DOS weight and balance program was an obvious application to use to do that. It was an on again, off again project that ended in 2016 but kept my aging brain active and did indeed teach me Javascript. You can reach the working Javascript Weight & Balance program here or use the link in the navigation panel. Like the old DOS program, it's available without charge to anyone wishing to use it.

I also use the domain for off-site backup, family stuff, and experimentation. It all results in the hodgepodge you see in the navigation pane. If you wish to visit a more meaningful and more focused site, check out my wife's website:

You can purchase “A World in One Cubic Foot”, his latest book, at Barnes & Noble and Amazon.com. A review of the book is at NPR.org.

Finally, if you use the Leaburg Dam bridge at milepost 24 on Hwy 126 east of Eugene, OR, take a look at:
