Not in the lava directly, but he's pretty damn close. I'm all sweaty from watching.

From youtube: "Sam Cossman and George Kourounis with volcanic pioneers Geoff Mackely and Brad Ambrose become among the first explorers to step foot inside the worlds most dangerous and inaccessible volcano, Marum Crater. More people have visited the moon than the firey bottom of this spectacular and deadly location."
