Here’s the direct link to balloon expert JP explaining the Chinese balloons. Note: in 2011, JP Aerospace launched a steerable balloon (dirigible) which reached 95,085 ft MSL, setting a new world record for dirigible flight. His 18000 free student experiments to the edge of space were launched by 200 or more separate balloon missions. http://www.jpaerospace.com.
