Unfortunately, this PRS10B won’t qualify for “wings” on this balloon flight. In the United States, professional, military, and commercial astronauts who travel above an altitude of 50 miles (80 km) are awarded astronaut wings. — Tom could qualify for the 2019 Global Space Balloon Challenge (GSBC) as “Best Science Experiment”. https://www.balloonchallenge.org/get-involved/prizes == “The other PRS10B Rubidium has a more interesting "trajectory". It is loaned to Tom Van Baak who will help fly it under a balloon in his quest to again demponstrate part of the General Theory of Relativity.”
