Fortune magazine was given a peek inside the 787 assembly line and the result is amazing. They have a 40 shot slideshow that is just jaw dropping. Best I can tell, these photos were taken early last week.There's also a video and article to go along with the photo essay.
UPDATE 6:44 AM: A little investigative work shows that the photos from the factory floor of Dreamliner 1, 2 and the Static and Fatigue airframes were taken on March 10 and 11. The Spirit and LCF photos from the flight line were taken March 20 and April 1 respectively. The photos from Japan were taken in late February.
