> Combustion or pyrolysis is expected due to aerodynamic heating. My naive impression is that this would not be possible. I would expect that a very light object with large sail area would be driven so easily by air flow that it would experience negligible heating from friction. What is the physical reasoning behind thinking it could burn up?
