Yeager famously survived an accident with a modified F-104 that was in some ways quite similar to the SpaceX craft (i.e. a plane with a rocket that can fly an arc up out of the atmosphere). Quite a few of these rocket-plane flights were considered spaceflight at the time, though they don't meet the modern (100km) definition.
But yeah, he's gotta be the luckiest person alive right now, being the only one surviving a space launch related accident while airborne.
