Now, a rare site at LAX: two 747400s departing backtoback. Delta Air Lines Flight 283 (N673US) to Tokyo Narita and Asiana Flight 201 (HL7428) to Seoul, Icheon. Delta is retiring their 747 fleet and Asiana now flies the A380 between LAX and Seoul ICN. Note: @ 1:05 you can see the dust thrown about by the Delta 747
