The ancient mechanism of Antikythera, a metal box with a complex bronze mechanism inside, whose purpose has never been discovered, is linked, in some way, to the mysterious “Philadelphia experiment”. In 1943, the USA subjected the ship Eldridge to an extremely strong magnetic field, in an attempt to make it invisible. The results for the sailors on board was terrible and lethal. However, one of them survived and, on him, the experiment was successful…
Martin Mystère investigating a project mentions story told by his friend Mister No about "Philadelphia experiment". In one vignette we even see Mister No during his adventure in Bermuda Triangle (Mister No 44-45, more info below). However Martin, knowing Mister No is not convinced about reliablity of that story!
During discussion with Martin, old widow Alexia tells him she come to him because he is famous with investigating supernatural and haunted things, on which Martin tells her she mistaken him for his London friend (aka Dylan Dog).
