I did the same thing in my CJ some years back. I had a pilot in the
back seat and handed it off to him with the usual stick-shake and 'you
got it'. We flew along for a bit and he entered a shallow bank which
turned into a spiral. Eventually I asked him where he was going and he
responded that he was just wondering the same thing. Neither of us was
flying the airplane.
Nothing like close to the ground tho'. You've got me beat on that story.

Excellent film. Did you see the extras? The producer talks about his love
of Spitfires, and I think that shows in the film's flying scenes. Also, I
think I'm correct in saying the pilots' incarceration was in their own
country, now occupied by Russia, which makes it even sadder. To have gone
through the war, and then have to deal with another 'war' when you get back
to the country you have been trying to free must have been very hard.
We are going to try watching The Aviator this week, tho' from what I've
heard, I'm not sure it will be as good as DBW...

Yakers,
I just got turned on to a great movie that you might enjoy. It is called
"Dark Blue World".
It is a WWII story about 2 Czech pilots that escaped to England to fly
Spitfires during the Battle of Britain. Of great interest to me was that the
story inter-twines the pilot's postwar captivity in Russia.
It has several really great, high quality digital Spitfire flying scenes-not
"computer produced". You will likely get some points with the spouse too, as
the movie is one of those "foreign" films...complete with subtitles! (Oh yes
.and it is a love story too...) Kelli enjoyed it!
I was not aware that the Czech and Pole pilots were considered a threat to
post-war Russia, and therefore held as prisoners...gives you a further
appreciation for our freedom, and the type of culture our aircraft came from

This may be obvious , but before you go out and spend some bucks on
parachutes, try the different varieties for fit in the airplane. CJ's and
-52's don't have major cockpit dimensions and are made for seatpacks.
Unless you're pretty small of stature, a backpack just won't fit. A
chairpack (a mix of seat and back pack) might. The seatpack chutes also
help with the legroom problem in both a/c. By getting up a little higher in
the seat (especially in a -52), legroom is increased substantially.
A static line for the GIB is a good idea. Maybe in front, too.

This is a REALLY dumb thing for me to even think about, but do any of
you guys flying an L-39 have a grasp of your actual hourly operational
costs? I am an A&P, & ex-jet fighter crew chief with my nice hangar in
my back yard, so the labor costs would be nil, but I was wondering about
actual operational costs. And what are you seeing in average fuel burn?

Only my 2 cents here. I used to be a skydiver and have around 150dives in
my logbook. Nothing wrong with square chutes. That is if you know how to
fly them! Square chutes are foldable gliders. They are inflated by the air
during opening and that is about all they have in common with "traditional"
chutes. One pilots a square chute by pulling on the ailerons connected to
the toggles. Landing such a foldable wing can be quite tricky. If one is
not properly line up to the wind, or if the flare is initiate too low, or
too high and the wing stalls (and deflates...) the results could be worse
then landing under a round chute.
Personally, I have a Strong 26feet Lopo ROUND parachute. As I said, only my
2 cents here.

--> Yak-List message posted by: "cpayne@joimail.com" <cpayne@joimail.com>
This morning at Waycross, some of us tested the Exhibition
race routine for Ops validity. Worked Great! Not real fast
but unlike REAL races, this on is on a tight course, closer
in to the crowd and features some vertical coming off the
pylons. Not good for speed but great for showmanship.
Having a takoff, landing and overhead race boss ("Pappy")
really did work. Both from a safety standpoint and control
feature. I wasn't sure that we could work on a 3 to 3-1/2
mile course but no problem, a triangle course might work a
little better with "racers" going up to 400 - 500 agl on the
back side and down "lower" in front of the Home pylon. No
more than 3 G's were needed, our only concern was getting
too aggressive on the pull down onto the crowdline straight.
Mostly it was great fun but don't try this at home without
lots of briefing and head work by participants. I laid out a
course and reviewed it with the Airport Manager for
approval, nobody got overflown and we stayed within the
immediate airport area. My thanks to Pappy, "racers" Bob
Langford in the -52, Wild Bill Walker in a 400HP -TW, and
Jay Land in a CJ. Tim Williams also backed up Pappy's
eyeballs from the back seat.

From bail out to "Whose flying?" The T-34 story reminds of how stable some
planes are. My first instructor Buck Greenfield, (Lic # 1888) showed how
stable airplanes are built. He trimmed up a Stinson 108-3, and he and I sat there,
while it landed by it self. His lesson? "Let it do most of the work."

I have to ditto this about the race. We tested this with a benign scenario
(no passing, at least 300' on the back of the course, etc.). Every one on the
ground said it looked great but needed to look more like a competition was
really happening. What we were looking for, was just how difficult, it would be
making turns down near the dirt. Also on how to start and stop the race plus
get an idea about how to pass two aircraft. A little more work needs to be
done, but should make a good act for shows.

We have occasional need to recharge the battery & it's location makes it a
significant ordeal. Does anyone have a line on a factory or home built external
power plug that will fit the outside receptor on the port side of a CJ?
