My Father in World War II

A B-17 crewmember, wounded and shot down over Sicily, a POW for two years. He escaped twice only to be recaptured. Read his story, see his Stalag 17 mug shots, see the MIA telegram sent to his parents, see an escape map that he drew, and learn about the crew by clicking on either picture.

How Would You Like to Fly Aboard a B-17?
You can!
Experience the sights and sounds of a vintage B-17. Feel the rush as you begin the take-off roll and four 1200-horsepower engines go to full throttle. Try to imagine how it must have felt flying into combat over occupied Europe for the first time. This is a once-in-a-lifetime adventure that you'll never forget. Here are three organizations that have refurbished B-17s that you can fly aboard:

Nine O Nine of the Collings Foundation:

Aluminum Overcast of the EAA Aviation Foundation:
On Wednesday, May 5, 2004, Aluminum Overcast was seriously damaged. The B-17 had slowed to about 30 mph following a successful landing when both main landing gear collapsed. The incident happened at Van Nuys Airport, Los Angeles, California. Aluminum Overcast has since been repaired and is on tour again.

Yankee Lady of the Yankee Air Museum:

The game of Sudoku has become very popular. If you enjoy playing the game, or if you've seen others playing it and want to learn about playing, then you'll want to download Sudoku Playing Palette.

Sudoku Playing Palette is a Windows® program designed to take the unnecessary work out of playing Sudoku. It doesn't play the game for you but it reduces the need to figure out what numbers may be played at each location. It eliminates the scribbling of notes inside the game. By relieving this tedious aspect of Sudoku, it allows you to concentrate on the correct logical choices. In short, it lets you simply play!

The starting point of a typical game is shown here. The large numbers are the numbers that you play. Simply use your mouse or the tab or arrow keys to go to a particular cell and enter or change the number as you like. The small numbers at the top of each cell are computed by Sudoku Playing Palette. They tell you the numbers--the "possibles"--that can be played at each location based on the rules of Sudoku. So you don't have to figure out what's possible! But it's up to you to decide what number should finally be played at each position.

The Help menu explains how to play Sudoku and how to use Sudoku Playing Palette. If you get stuck, you can choose from 3 levels of hints: Gentle Hints, Strong Hints, and finally, the Answer! You can save a game and recover it to finish playing later. If you don't like the default colors, an option is available to change the colors. If you change your mind after entering a number or series of numbers, you can Undo. If you change your mind again, you can Redo. If you like solving Sudoku on paper, simply enter the starting numbers into Sudoku Playing Palette, let it compute the "possibles," and print the puzzle. Other options are also available to make the game enjoyable for the individual player.

To download Sudoku Playing Palette, click on the example game below, or go to the downloads page where you can find additional programs available for downloading. The file is in ZIP format. You can unzip it using WinZip® or another utility designed for extracting Winzip files. Sudoku Playing Palette is a free-standing program so no other installation is necessary.

PLEASE NOTE: Sudoku Playing Palette is available "as is" with no guarantee that it will suit your needs, no guarantee that it will not cause problems on any system on which it is used, and no guarantee against consequential damages. This game is not supported and might change from time to time without notice. Translation: You're on your own.

My Background and Some of My Specific Interests


I am a retired Electrical Engineer with more than 35 years of experience covering a broad range of areas, including analog circuit design, digital circuit design, hardware systems design, software design, and algorithm design. I hold BSEE and MSEE degrees, a Professional Engineer license in the State of California, a General Radiotelephone Operator license, and a California Community College Instructor Credential (Life) in two subject matter areas. I am also a Life Senior Member of the Institute of Electrical and Electronic Engineers (IEEE).


From March of 1966 until October of 1969, I served in the U.S. Air Force where I was trained as an Aircraft Radio Repairman. After Tech School, I worked on F-105 Thunderchiefs and F-4 Phantoms. The F-105 and F-4 were all-weather fighter-bombers and major players in the Vietnam War. From the beginning of the war, through 1969, the F-105 dropped more tons of bombs on North Vietnam than the B-52.

From October 1968 to October 1969, I was assigned to the 388th Avionics Maintenance Squadron of the 388th Tactical Fighter Wing at Korat Royal Thai Air Force Base, located near Korat, Thailand.

You can see some of the sights at 388th Avionics, Korat RTAFB, Korat, Pi Mai, and Bangkok if you click on the pictures below.
