Here is some more to add to Paul's excellent post:

Paul and I had flown the earlier part of the day team flying for about
3.5 hours or so. We had worked our way from the local foothills and
eventually ended up about 30 miles away over the rugged snowy peaks at
the end of the Skykomish Valley; and the start of the Stevens Pass
highway. This was pretty good considering the day was somewhat windy
and the building high pressure was starting to affect the thermal
activity.

anticollision devices for gliders.
