SCENE: One of those Christmas holidays spent with the Hartills in the 60s.
PROBLEM: What is it about the brain that refuses to cooperate when you are
trying to remember the name of an old cowboy singing about his dog "Shep"
and all of us laughing at the absurdness of Inza leading everyone into a
belly-rolling, tears streaming down our face laughter. Thank God the brain
lets me remember the heart-warming moments of life with people like Inza
Hartill. Oh yes, his name was Walter Brennan, thanks Craig!
My two daughters always called her Aunt Inza. Like I said, we
spent a few holidays with the Hartills and one of Inza's specialties that
I always looked forward to was a big serving of rutabagas (turnips) with
black pepper tossed on ' probably a result of Bill's New England
upbringing! Then, of course, there was the sweet corn and beer Bill and I
had after a summer flying session at the Basin. Inza would husk the corn and
put a little sugar first in the boiling water. It was one of her sweet
touches. Of course we didn't tell her we got the corn from the Basin
along with Jim Patterson, but that's where our Wakefields landed - in
the darn corn.
Lanark Park in Canoga Park was the place to be on the Fourth of
July with Inza and family. She would always have the best goodies to eat
for a summer evening of watching the fireworks.
There were also competitive moments in heated croquet games in
the back yards that would end in pure thirst quenching bliss with her
Inza always made sure her boys were ready to shag after one
of Bill's long flights, whether at the Basin, Taft, Texas, or where
ever. She ruled with a firm hand. Just ask them!
I cannot think of seeing one sad moment with Inza, there was
always a great laugh and huge smile to boot. I'm sure there are many
other moments to remember in my friendship with Inza and Bill, but they
will have to wait until a Fourth of July evening in Lanark Park sometime down

Visualing Shock Waves While Flying
Here is something to think about on your next east-west flights.
For many years I have traveled from coast to coast to wind tunnels for
monitoring the test for newly designed aircraft models and bring back
the results. Somewhere along the way I got to noticing a long narrow
shadow on the wing, starting at the fuselage and going sometimes to the wing
Eventually I realized that this must be the shadow of the shock wave
over the wing. I found that when I saw the shadow, the sun was on the
other side of the plane. So, going east when the sun from the right, the
shadow will be on the left wing. The opposite direction show the shadow
was from the right wing. I soon got to choosing a seat so as to see
the shock. Take a picture.
While coming back from the momentous World Championships in France,
1987, Bob White was in a seat aft of the wing leading edge junction
with the fuselage. I had mentioned the shock wave shadow to him. He came
back to me and asked me to look at what he saw. Looking along the
leading edge, there appeared a jagged leading edge. It told me that we were
looking through the standing shock wave of the wing. There was no sun
shining at the time.
I generally ask the pilots if they will be exceeding Mach 0.8 during
the flight. If so, there is a chance of seeing either of these things.
ROW at the NATS...
Well, I guess we have some controversy about the NATS....Guess that means I
have to say something...
The question was asked about who is to "blame" for the ROW "pond" ( I hate it
when a volunteer is blamed for something). Seeing that I was the contest
director, ultimately I am. However, (and I think most everyone knows this)
the entire Nats is handled by NFFS representatives and volunteers. AMA
supplies the facility, the maintanence people, the AMA trophies, and other
misc items. AMA doesn't look over our shoulder and micro manage anything. If
it is done correctly, then I (we) did it right. If it is done incorrectly,
then I (we) did it wrong.
I will tell you that building a ROW pond was not on the top of my list. It was
constructed with materials available and seemed to have met the requirements
set by the Event Director. He deemed it acceptable and everyone flew off of
it. I did not hear any complaints about it and it sure looks like there were
many acceptable flights off of it.
To be truthful, I have to agree with my buddy Bob Gutai. If anyone is unhappy
with anything that has taken place, there are a few ways to take care of
that. One is to contact the past CD (me) or the new one and calmly explain
what the problem is and a possible solution. The other is to grab the
whatever by the horns and volunteer to run the event. Of course, you wouldn't
be able to fly that event but you would have nearly total control over what
We tried our hardest to please everyone and let me tell ya, it is da&* hard to
do. Just finding an acceptable launch position is nearly a full time job. Then
there is making sure that all the volunteers have what they need. Tabulating
scores, making sure everyone has tables and chairs and pencils and water and
tents and cups, etc...The list goes on. Luckily we have some excellent people
that give up their flying so that the majority can enjoy the sport.
I think it should be high on everyone's list that one time in their FF career
they should give up one day of flying at the nation's biggest free flight event
and cross over to the other side of the table. You get a whole different view
of what goes on. Thankfully, I was surrounded by these great people and it
all turned out OK.
So, it sounds like next year we need a bigger pond. Simple as that. Can be
done. Nothing is impossible. After all, we are free flighters.....
NFFS is off the water
Re: ROW Pond at the Nats
The Nats is run by members of the NFFS with the assistance of the AMA. The
proposal to run the ROW event was made by Abram VanDover and Dave Thomson, who
constructed the pond. That is was not large enough was evident when it was
installed, but given the amount of time remaining, it was not possible to
enlarge it in time for the 2005 competition. Both men have pledged to have a
pond at least twice the size for next year, and I believe them. Since the
ROW event has not been run at the Nats for many years (before it was moved
to Muncie), I for one am pleased that it was on the venue at all. Next
year, Bill Vanderbeek is sponsoring the One Design Hydro Star event to
coincide with the ROW event.
If everyone would just calm down and consider that this was a learning year
after a long hiatus, then we can enjoy an event that is both fun to fly and to
Update on Jim Bradley - Sun. Aug. 14
Hello everyone - part 1,
In case you have not heard, Jim had to go back into the hospital
because of fluid buildup in his lungs and blood in his urine. To make a
long story short, his artificial heart valve had come loose and was
leaking badly. After many tests, he had to go into open heart surgery
again Tuesday morning. The repair was successful but they could not stop
the bleeding, possibly due to the blood thinners still in his system.
That afternoon, the surgeons had to go back in to see if anything was
wrong. They found nothing out of the ordinary, so they sewed him up
again. The bleeding continued all Tuesday night and his condition was
considered critical. He was on a respirator and still unconscious. The
all-night nurse gave him 20 transfusions! Wednesday was not much better,
but by Thursday the bleeding was stopped and he was taken off the
respirator. According to Linda, by Thursday night he able to talk and
seemed to ! have no major problems, so he may be on the road to recovery
now. He is still in the critical care unit, but things are looking
better. That is all I know at this point, but will keep everyone posted.
Hello everyone - Part 2,
Jim is continuing to improve. They have him walking around some and
they are giving him limited physical therapy. He is still in intensive
care, but his condition is slowly improving. Let's keep our collective
good thoughts together for a continued recovery.

Looking for Black/Gray Rubber
This is Artem Babenko
I ask everyone who have dark-grey FAI rubber (1mm/3mm in thickness), which
was used in the early 90s in F1B. I would like to buy it

glider I calculated vertical velocity on 3.6 m/s, which matches the above
figures well. My own F1B models show sinking speed of 2.8m/s.

i tend to agree with the alien.
if you don't like the way things are done at the nats
instead of standing around sniveling about it do
somthing to make it to your likeing.
but than again if your row can't ger airborn within 15
feet maby you should just leave it in the box and do
some hanger flying.
Jim Bradley Update - Aug. 16th
I am happy to report that Jim is doing much better. He has a private
room (Florida Hospital - Orlando, (407)303-5600, Room 3353) and is
walking around more every day. His platelet count is 87, and when it
reaches 100 they will let him go home, which may be Thursday. He still
tires easily, but continues to improve. He is already talking about
going to Palm Bay for the F2C team finals and the Fla. State Meet on
Labor Day weekend! That sounds like the old Jim we all know.
