each presents a different hostile interstellar empire - Central Empire, Heart Stars and Green Exarchy;
Haertel encounters Martians whereas they are long extinct for Loftus and not mentioned by "Dirac";
the Martian "canals" are natural for Haertel but artificial for Loftus;
Haertel appears in the first diptych and is mentioned in the other two;
his space drive is anti-gravitic in the Haertel diptych but powered by a hydrogen-fuelled Nernst generator in the Loftus diptych.
Alternative possibilities are explored systematically. Today, I will be away from a computer but will finish rereading the Haertel novel, Welcome To Mars.
