Air molecules dashing into other air molecules that are stuck on to the surface of an aircraft. Air density can be lower than it is on the surface of the earth, there's still plenty of air molecules to bash into one another. So like other very, very high speed aircrafts, and like re entry vehicles, they've been designed,. their surfaces chemistry has been really particularly designed to be able to cope with that happening on their surface. That's why, you know, heat, heat and shields are so importante.
What are Van der Waals forces? Neil deGrasse Tyson and co-hosts Chuck Nice and Gary O’Reilly explore the fascinating world of surfaces, biomimicry, and Formula 1 with physicist and author of Sticky: The Science of Surfaces, Laurie Winkless.
