This video was produced earlier this year by United Airlines. In a time lapse sequence, it shows the remodeling of "the first and business class cabins on its Boeing 747, adding new lie-flat beds and 15-inch personal TV screens that have more than 150 hours of entertainment."
(I don't know why I love stuff like this, but I do...)
