I believe the pressure calculations assume that there is an infinite
amount of air available to fill up the whole after it is drilled. 
With such large pressures, there may not be enough air in the earths
atmosphere to ignore the effect of the loss of air from above ground
into the hole.  As long as we are having fun calculating, how big
(diameter) does the whole through the earth have to be in order to a
"significant" amount of the atmosphere into the center of the earth?
 This begins to sound like a good plot for a bad sci-fi movie.
