What specifically were you looking for relating to polymers?Can anyone recommend a comprehensive polymer book?
It's a nice example of how far above an "aerofoil" (i.e. the mountain) the airflow is affected. Even in the UK, where the hills are mostly under 3000 ft, the gliding altitude record is over 38,000 feet, and flights to 10,000 feet are not particularly special. Records for the duration of flights are no longer accepted, because with modern equipment the main issue is how long the pilot can stay awake, rather than flying skill.Wow, interesting glider article!
