Well, yes, but how long would that have taken - half an hour, an hour tops? My point is that Supes can zip around the world in no time flat - he's almost as fast as the Flash, forcryin'outloud - so a leisurely interview somewhere on an uncharted island is no obstacle to his making his way back to the White House on time - even if he DOES dawdle a bit, he can be there virtually immediately, so who cares? Anyone who can travel all over the world stopping tidal waves and saving sinking cruise ships without his boss getting annoyed because he's been away too long should have no problem with a measly trip to the mid-Pacific and back.
