The flick of a switch
I worked on the design of the AIM-9M, an improved version of the air-to-air heat seeking Sidewinder missile. The particular improvement of the 9M was the addition of counter-countermeasures to ignore decoy flares ejected by the target aircraft. I worked on fine tuning the electronic design through extensive lab and field testing.
One testing technique used an analog computer model of the missile circuitry and simulated input from a target jet engine, interrupted by the appearance and trajectory of the decoy flare. We measured success by the ability of the guidance electronics to ignore the flare and continue tracking the target.
Another technique was to use the actual missile electronics on a rotating table to simulate the trajectories and dynamics involved.
For field testing we set up the missile in a stationary ground station out in the desert and had jets fly over dropping flares. It was rather detailed work, and we typically worked through the night setting up the test for the following day.
But the ultimate test was shooting the missile at an actual target, which we did once (while I was there). The target drone, an old F86, was flown via remote control and the shooter was an F4 flown by a Navy test pilot. We planned the flight paths and trajectories, and stipulated two flare drops at two and three seconds after the missile launch.
When I think of all the effort and expense setting up this test I still marvel at some manual means of execution. In particular, I had the task of operating the remote control switch to release the flares at the appropriate two and three second marks. Needless to say, it was a very stressful, nervous responsibility as I would be such a flagrant goat if I botched it. As the time for missile launch arrived the test pilot screamed "Fox, Fox!!" over the radio, which I later realized signified missile launch. This caught me off guard, as we hadn't practiced this detail and I thought something was amiss. But, fortunately, I went ahead with my "thousand one, thousand two - flick -thousand three - flick" of the switch, and the test ended up a great success. Looking at the detail data afterwards it seems the first flare was about 1.8 seconds, followed by the second around 2.6 seconds, the time acceleration no doubt a consequence of the heightened excitement.
But I was so relieved afterwards, both about the test success and doing my job okay. Oddly, after all these years I still feel stressful when I think about this experience, and I think I've had some nightmares about it. Maybe my version of combat PTSD. In retrospect I can hardly believe they left such a crucial job to an inexperienced junior engineer. One of the managers was standing behind me, so perhaps he would have intervened if I botched it.
I spent a memorable and satisfying two years at NWC before deciding I preferred the private sector and went to work for HP in Boise, ID.

2011 Book Round-up
I read 58 books in 2011. Here are the top six in terms of impact or enjoyment.
The Forever War – Dexter Filkins
This covers the author’s experiences reporting the wars in Afghanistan and Iraq. While I have to give this an “R” rating for violence and some profanity, this was a very impactful book for me. While the author didn’t promote an “in your face” political agenda, it still left me appalled at various US missteps that had such drastic consequences for everyday Iraqis. And I wonder about the prospects for pushing democracy on some cultures. But mostly, I ached from the tragedies imposed on normal Iraqi (and Afghani) people, and am in disbelief what awful things some humans can do to others, especially by presumably pious people in the name of religion.
The Journals of Addison Pratt – ed. George Ellsworth
While a dramatically different time (1850’s) and place (South Pacific), I was struck by the similarities in Addison’s missionary experiences and feelings to those of my own. And what a normal, rational person he was (not some fanatic religious zealot). It felt like he would be at home in the modern Church. His earlier life on whaling ships read like Moby Dick. His lengthy separations from, and longings for, his wife and children were heartrending.
The Life and Times of the Thunderbolt Kid – Bill Bryson
While a humorous and clever book in its own right for any reader, I was propelled back in time to my childhood from the same period as the author, and so many things and experiences resonated with me.
Doc, the Rape of the Town of Lovell – Jack Olsen
I know, how could such a book make it on my reading list, much less my top list. But on several levels this was a fascinating and impactful account for me. As a bishop, I wondered about how the Church leaders handled things. I was dismayed how the victims were treated by so many, and the doctor supported by so many. I worried how justice could be served, with so many things stacked against the accusers.
Stiff – Mary Roach
A really off the wall subject—dead human bodies. But dealt with by the author in both an amusing and enlightening way. I went on to read other books by the author, but this one was a notch above. Not for the squeamish, though.
Give a Boy a Gun – Jack Olsen
The story of Claude Dallas and his murder of two F&G officers. Very interesting story about a variety of fascinating people. Especially interesting to me as it was in our backyard and dominated Idaho news at the time.
Here are the honorable mention books:
Mayflower: A Story of Courage, Community, and War – Nathaniel Philbrick
A rather virgin subject matter for me, and this went far beyond the ship and voyage, and continued for a couple of generations of interaction and impact between settlers and natives. A huge percentage of settlers died the first year from illness or starvation.
Nothing to Envy – Barbara Demick
All I can say is “wow”. North Koreans have had, and still have, it very rough indeed.
The Painted Veil – W. Somerset Maugham
Poignant story, and the ending differs from the movie (I liked the movie ending better)
Columbine – Dave Cullen
Fascinating, and a bit disturbing.
In the Heart of the Sea – Nathaniel Philbrick
Adventure and peril in the extreme
The Looming Tower -- Lawrence Wright
Very insightful recounting of people and events of the rise of radical Islam leading to 9/11.
Panzer Commander – Hans Von Luck
An interesting and different look through the German army lens at WWII battles and fronts, and the tragic aftermath of many imprisoned for years in Russia.
Moby Dick – Herman Melville
To the Ends of the Earth – Robert Kaplan
I love his adventure travels and commentaries
Inheriting Syria – Flynt Leverett
Reads like an extended report assignment, but interesting in a narrow sense of understanding the modern Syrian regime.
Malcolm X – Manning Marable
The man had some serious flaws, yet a knack for inspiring.
In Cold Blood -- Truman Capote
Interesting treatment of a tragic crime and tragic perpetrators
Harry Potter and the Sorcerer’s Stone – Rowling
Harry Potter and the Chamber of Secrets - Rowling
Harry Potter and the Prisoner of Azkaban – Rowling
Harry Potter and the Goblet of Fire – Rowling
Harry Potter and the Order of the Phoenix – Rowling
Harry Potter and the Half Blood Prince – Rowling
Harry Potter and the Deathly Hallows – Rowling
I read these as virgin territory long after everyone else, so didn’t have to wait for the next installment. I enjoyed them more than I thought I would, and they evolved from lighter YA literature to more mature and complex circumstances. By book 7 I had my fill.
The Help – Kathryn Stockett
I particularly enjoyed this audio rendition.
The Perfect Mile – Neal Bascomb
Learned a lot about the legend and legendary event(s).
The Darkest Summer – Bill Sloan
Desperate and historic times early in the Korean War.
The Four Horsemen of the Apocalypse – Vincente Blasco Ibanez
Fiction, yet grounded in the times and events and people of WWI.
These were interesting or enjoyable enough, but another notch down for me:
Snow Falling on Cedars – David Guterson
Hiroshima – John Hersey
The Big Rock Candy Mountain -- Wallace Stegner
Spook – Mary Roach
Bonk – Mary Roach
Packing for Mars – Mary Roach
Last Stand – Nathaniel Philbrick
Without a Doubt – Marcia Clark
The Number One Ladies Detective Agency – Alexander McCall Smith
Rocket Men – Craig Nelson
Sometimes a Great Notion – Ken Kesey
Baghdad Without a Map – Tony Horwitz
Vietnam, A History – Stanley Karnow
Hot, Flat, and Crowded – Thomas Friedman
The Ghost Map – Steven Johnson
At Home: A short history of Private Life – Bill Bryson
Son – Jack Olsen
My Father, Maker of the Trees – Eric Irivuzumugabe
A Walk in the Woods – Bill Bryson
Six Armies in Normandy – John Keegan
The Professor and the Madman – Simon Winchester
Shakespeare – Bill Bryson
Far from the Madding Crowd – Thomas Hardy
On Mount Hood – Jon Bell
These weren’t worth the time:
Skyjack, The Hunt for D.B. Cooper – Geoffrey Gray
Author jumped all around, ultimately had nothing to add to solving the mystery, and seemed sucked into all the conspiracy kooks.
Notes from a Small Island – Bill Bryson
I like and enjoy Bill Bryson, but I couldn’t get into this account of travels in his adopted UK, and found it just too mean spirited too often.
Judas Gate – Jack Higgins
Churchill – Paul Johnson
Helmet for my Pillow – Robert Leckie

The memory lane of slide scanning
I finally borrowed a Nikon slide scanner, with an automated tray, so my holiday project has been to scan all the slides and convert them to digital format. It is a lengthy, tedious process but at least, with the automation, I can walk away and return an hour or so later to load the next batch of 40 slides. Other than the occasional jam, it is a marvel of technology.
One thing I am immediately struck by is how awful so many of the photos are. The Rollei was completely manual, for focus and exposure, and had a fixed lens. Focus is often bad, and exposure was hit or miss. Inside shots are habitually underexposed, and when a flash was used the lighting was harsh and cast shadows up the faces. Very unflattering.
But in spite of all these technical faults, I have been launched down memory lane, and am reveling in the past. I am struck by how cute our kids were, and what a charming little growing family we were. Suzanne and I were once young and energetic. We had such good friends and visited (and lived in) such interesting places. We moved into new homes and landscaped them, built fences, wallpapered rooms. We shoveled snow from driveways and walks, and hosted family members at holiday times. We had Christmas nativity scenes with costumed kids playing various roles through the years. We had siblings holding newborn additions to the family. There were softball teams, birthday parties, school plays, family reunions, campouts, quilts (Suzanne's handiwork), first steps, Halloween costumes, and so much more. And I'm only up to 1984!
Well, as Jimmy Stewart says in the movie, "It's a Wonderful Life". That's how I feel.
Here is a sample photo from 1983.

Wondrous Christmas Music
Here are a few of my favorites, leading off with perhaps my all time favorite:
Here is the opening processional from a few years ago. If this doesn't get the energy flowing I don't know what will:
This one took a few listenings to grab me, so hang with it. About 2:30 it really kicks up a notch:
The finale "Angels from the Realms of Glory" from last year's concert (Miriam and Magdalena should enjoy the dancers):
The same finale from the prior year. Note the choir member with tears at 4:02. I can only imagine how powerful this rendition is live:
Mack Wilberg, the arranger for these selections, is my all time hero. I love pretty much everything he has a hand in.
I hope you enjoy these as much as I do, and Merry Christmas!

Return to Slovakia -- Iron Curtain, Part 5
Juraj Bubnas and family.
We continued eastward and enjoyed hiking up to Spis castle, an impressive edifice, though a bit mismanaged and not quite tourist friendly. For example, there was loud pop music playing in a concession area in the center of the castle, and we found the gate locked as we attempted to exit the castle on the path back down.
While there were no expressways in the eastern half of the country, we did find the roads decent and well paved. However, the Slovaks are dangerous drivers, routinely passing in curves and other blind spots. Several times we came upon accident scenes. It was rather unnerving. One strategy was to follow behind another vehicle so at least you wouldn't be the one in the head-on collision.
We took a chance and checked into the Hotel Chemes upon arrival in Humenne in the far east of Slovakia. It had a few rough edges but was quite satisfactory, given the very reasonable price. In fact, prices seemed depressed for everything in Slovakia. Unlike, say Prague, Slovakia is a very low key and economical destination for tourists.
Once again we were welcomed with opened arms by many of Suzanne's cousins in the Humenne and Poruba areas. What gracious and friendly people. They held an outdoor party for us and numerous cousins came by. Bridget and Jeremy were particularly popular speaking Russian to those of our generation and older (who learned Russian rather than English).
It had been five years since our first trip to Slovakia, and we felt like the country was definitely moving up in the world. Still off the beaten path but a more pleasant, upbeat feel to it.
Here is a blog post by Bridget describing experiences from this trip.
And last year we returned for a quick drive through Hungary and Slovakia, again visiting the same cousins. I wrote several blog posts (here, here, and here) about that, as did Suzanne.
There is a lot to like about Slovakia, and the other former Eastern Bloc countries. Some day we'd like to go back and spend more time hiking and sightseeing.
