One slight issue is the authors tendancy not to do his research
i.e.=20
'1,000km flights haven=E2=80=99t been easy to come by,

flown in North America in December. '

Never let the truth get in the way of a great article eh?

Satellite loop photos this AM (12/20) showed the Chinook wave
setup from

north of Calgary all the way to Yellowstone.

The Cninook Arch wave system is generally thought to be a larger
scale
phen=

have seen a
sa=
tellite image of a crisply defined Chinook Arch stretching all the
way
from=
Anchorage Alaska to Denver. To my knowledge, the only serious
campaign
to=
connect with the Chinook Arch was by Tim Wood, self-launching
out of
Pinch=
er Creek.

What Chester Fitchett (and co-pilots Guy Peasley, Patrick
McMahon, Gerald
I=
nce) and other CuNim members - always a risk to start naming
names - have
d=

accomplis=

out of
CuNim=
and Cowley, and Vaughn Allen self-launching out of Claresholm.
The best

published to date

is by Vaughn, published in Free Flight, the Soaring Association of
Canada
m=
agazine (my apologies for not provided a direct link; the search
feature

As Chester says,"Plenty to learn", more to come.



Tony Burton did a few limited 'research flights' in the Alcor sailplane
along the Chinook Arch https://en.wikipedia.org/wiki/Lamson_L-
106_Alcor -wrote an article if Free Flight. As you say Vaughn's
article's are the best -he was the first guy to fly 1000 km in the
Rockies Wave a long time ago in his Pik20e! Also have to remember
there have been 5 flights flown in the Columbia Valley, the other side
of the Rocks over 1000 km including Canada's longest to date
1175km. East or west still plenty more to learn and to come? -
1500km triangle in B.C. ? 5000KM in the wave/Arch?
