New c/scheme (in 2003).  This aircraft is a bit special in that it first flew on 29-Apr-88 and was the B747-400 prototype with Pratt &amp; Whitney engines (as N401PW).  It was delivered to Northwest in Dec-89 and was transferred to Delta Air Lines during the merger in Oct-08.  It continues in service with Delta today (Feb-13).
