Hi Adam,
Let me start with a story that belongs in the “most embarrassing travel moments” hall of fame—but I’ll bring it back around to CKD in a minute.
It was the middle of winter on a 14-hour haul from China back to the States for my parents, who were teaching in Beijing. They were in first class—pillowy seats, glowing screens, and just enough legroom to feel smug about… until you drop something and watch it vanish into the black hole of airplane carpet.
