I've designed a logo for GPSL but arranged to leave the diskette at
home. I'll post it tomorrow. I'd like the motto for this year's GPSL
to be, "100,000 feet. Been There, Done That".

Paul is doing the vast majority of the work to put GPSL-2002 together so I
will bow deeply to him and accept this motto.

However, we should understand how unusual it is to reach 100,000ft. In the
process of collecting data for discussions about Mean Zonal Winds
(http://users.crosspaths.net/~wallio/MZW.html) and Ascent Rate Variations
(http://users.crosspaths.net/wallio/ASCENT.html) you folks sent me a lot of
flight data for missions past. For Mean Zonal Winds I accepted mission data
from before and after SA was turned off on 02May00 and we have a total of 54
missions in the study. Only 4 of those missions went above 100,000ft which
is 7.4%.

For analysis of Ascent Rate Variations I only used data from missions after
SA was turned off. There were a total of 28 missions in the study of which
only 2 went above 100,000ft. Again, that is 7.1%. This indicates we are
not flying higher as time goes by.

It appears we should not be overselling our collective ability to make it to
100,000ft because it happens less than 1 flight out of 10.

I think most of us have the *ability* to get to 100,000 ft, but
some of us have not tried very hard on most flights.

The baseline for a 100kft effort, when you're lifting more than
2-3 lbs., is a 1200g balloon. To me, anyone flying less than a
1200g balloon with more than a flyweight payload is not expecting
100kft. For NSTAR, I've flown only 4 1200g balloons in 10
flights (none larger). Three of these four were deliberately
overfilled to decrease the flight distance, which means that I'm
0 for 1 (01-B) in actual attempts at 100kft.

It would be interesting to see the numbers for 1200g-and-larger
balloons flown. I believe everyone at GPSL is planning to use
1200g.
