Dutch Aeronautical Association president Cornelis Kolff said "The Queen showed an extraordinary interest in the whole subject." The Royal Netherlands Air Force Chief of Staff, Lieutenant General Haye Schaper said "The man's a pathological case." Time magazine reported that the Amsterdam newspaper de Volkskrant said: "Once again, Queen Juliana's weakness for the preternatural had landed her back in the headlines: she had invited to the palace a crackpot from California who numbered among his friends men from Mars, Venus and other solar-system suburbs."

Adamski claimed in his books that these "alien humans" came from Venus, Mars, and other planets in Earth's solar system. However, none of the planets he mentioned are capable of supporting human life, due to their adverse environmental conditions. The first alien Adamski claimed to have met was from Venus, yet the atmospheric pressure on that planet's
