Suffice it to say that if the A380 doesn't sell, they'll be able to use it as the central feature in a waterpark.
But why does everyone get so excited about 850 pax? Even when the A380 operates at max pax load (which nobody plans to do for years) it's a smaller relative jump in size than the 747, in its day.
Have we all turned into nervous Nellies in this business? Or have some people taken too generous a swig of the tainted Starbucks?
