It looks as if the sales may range from 3,000 to 5,000 aircraft, from what we've been told.
I'd like to pick up on a question of cost. In 2007 you sold Saudi Arabia 72 aircraft for $8.86 billion. That would come to about $123 million per aircraft. Last week we were told that the F-35 would cost $70 million to $75 million per aircraft in 2010 to 2002 dollars. So we're looking at $70 million or $75 million for the F-35 and $123 million for the Eurofighter. There seems to be quite a discrepancy in cost there.
Can you tell us about that?
