500 (and 14)

The Boeing 787 Dreamliner broke the half millennium mark yesterday with an add on order by JAL:

From Boeing: The JAL order for five 787-8 airplanes, in addition to several orders from unidentified customers, brings the 787's order total to 514 airplanes from 43 customers since its launch on April 26, 2004, making it the fastest-selling commercial airplane in history. This increases JAL's total 787 order to 35 airplanes from their previous order of 30 in December 2004.

Along with a potential special paint scheme expected to fly with JAL (pictured here), there seems to be a distinct question as to whether or not the 787 can hold this impressive title for much longer. It's older (and shorter) brother the 737 Next Generation, holds the title for fastest selling jetliner by delivery date. When the first -700 NG was delivered to Southwest on December 17, 1997, the NG program had accumulated a very fitting 737 orders.

With that being said, by May 2008 when the first 787-881 is delivered to ANA the title may be revoked if Boeing hasn't booked 738 firm orders. Why not shoot for 787?
