In a sad day for old airplane lovers, Northwest will retire its last 12 DC-10s by January, 2007. The DC-10s joined the fleet starting in 1972, and if you’ve flown one of these bad boys recently that will not come as a surprise to you. In an age where some airlines offer hundreds of programs on demand, and live TV in coach, the DC-10s were still projecting one movie on a wall 15 rows ahead of you. I last flew one on Northwest from Paris in 2002, and while it had seen better days, it reminded me of when I got to fly as a kid. On the plus side, they’re being replaced with A330s and 747s, which have much better in-flight entertainment.
