Ever seen a glider hover to a standstill? Today's wave conditions ensured the surprising sight of gliders practically "sitting" in the air. It's strange enough from the ground, but quite eerie in the air. Here's a clip from today's footage, showcasing the effect.
Launching in the next hour or two, towing up to around 50K feet (higher than typical airliners fly), then hopefully #soaring in mountain wave to a new world record, at altitudes similar to the service ceiling of the (powered...) U2 spy plane.
