Hi !
The Phantom could, some times, not crash itself ... We succeeded to make it crash by trying more than half an hour because it can escape, or fall in the water (and the pilot dies by then) , so it's quite hard to do that grunt get out of its Phantom !
But what i could say : in theory, the Phantom is pilotable, by the same way we use for Wraiths or Banshees (by killing the pilote when putting RB or B button) . But it's in theory , because for the Wraith or the Banshee, we can see the pilot (or elements of the pilot), whereas, in this case, we actually don't know where the cockpit exactly is, and where we could see the pilot.
I didn't put an other information about this Phantom in ODST : if it crashes and if you put RB or B button (it depends of your configuration) , it will turn and turn, like it wants to be "on its feet", like Warthog or other vehicules.
I don't think it is pilotable, but we could try, because of the fact that, and you can see that on the video, the Phantom without pilot appear "blue", like pilotable vehicules !
