Query: Hessian measures in the aerodynamic Newton problem   Simple natural proofs of all known results regarding the aerodynamic Newton
problem are obtained. Additional new theorems and new promising formulas in
terms of Hessian measures are found. We would like to express our deep
gratitude to Gerd Wachsmuth for his very important comment which turned one
result upside down. Please ignore version 1 of the article.
