    ...it has to be cheaper than flying a 747 with a giant hole in the side of its fuselage.

I really doubt it. This thing has to have significantly more dry mass than a 747, and it's got two extra engines burning fuel. Plus, that telescope is going to cause a bunch of drag no matter where you put it.
