There’s always been something in the air with Mad Men, quite literally. From Mohawk to American, North American Aviation, and Ted’s own little two seater, airlines and aviation are about as prevalent on the show as aliases and fake identities. Even when Joan was upset after being served divorce papers from Dr. Harris, it was a model airplane she grabbed and threw at the unassuming receptionist as Don stood in the doorway. Mad Men has been telling us how the story ends from the very beginning. It ends on an airplane.
This Mad Men theory is outrageously absurd, yet disturbingly plausible.
