Here's a screencap of the newspaper clipping. The man's name begins with J and last name ends with "antham," which as far as I know isn't a name we've heard. But hey, there's three seasons left.

Also, it's been tracked down that the newspaper Jack was reading on the plane was the April 5 L.A. Times (the real one, as in the front page we see is a page from that day's actual LAT). If that's not an oversight (and on this show, what is?), it gives us a time frame -- the plane crashed in, I believe, September 2004.
Also, inside sources tell me next season they will have to play the Harlem Globetrotters to get off the island. ;D
