Aha! Evidence! Proof! The terrorist birds who took down US Airways Flight 1549 thought they’d covered their, um, air tracks. They crashed the plane in the Hudson and sunk the engine into feet of muck at the bottom.

It’s as if they’d left a signature — the one-word calling card of a team of would-be serial killers:
BIRDS.
