Hans Boehm was a German pilot who appeared only in Flight 714.
Boehm was employed as the co-pilot of a private jet by the famous millionaire Laszlo Carreidas, the Carreidas 160. He was also one of the hijackers of that flight, along with colleagues Spalding and Paolo Colombani, while working for Roberto Rastapopoulos. Boehm, along with the others, including Rastapopoulos, was taken to an unknown fate by aliens. However it is highly suspectable that he is alive as Rastapopulus and Allan appeared alive in Tintin and Alph Art.
