[Torchwood] Where was the Doctor during the events of Miracle Day? What happened to his companions (specifically the Ponds and Sarah Jane's gang)?

Perhaps because the event was so Capt Jack centered, intervention would result in the Doctor encountering Capt Jack, something the TARDIS hates as he is an impossible thing (and maybe by extension all humans impossible things, due to the events of the day).  If we believe that the TARDIS chooses where the doctor needs to be, it simply sorta steers him away from this event.
