Tom goes on to say:
"On occasion a creator had him call the hammer, but those instances were mistakes. Especially given the parameter that he needed to touch the hammer once every 60 seconds in order to remain in his godly form on Earth, the idea that he could just summon it to him in those circumstances doesn't make any sense. Typically, those mistakes were people misunderstanding the mechanics of how the enchantment on the hammer worked. (The film also gets this wrong at a crucial moment.)"
Writers who have had Thor summon or mentally control the flight of his hammer (off the top of my head):
Dan Jurgens (who Tom edited)
Also the guy writes the Avengers cartoon.
Is there an interview or an article where he says this you could link me to? Thanks
