There's a pretty tight parking area on the Eastern side of the runway, bounded by a fence. I reckon he clipped a bit of it as he taxied out. The normal parking in front of the terminal is no longer accessible after the lava flow across the runway.
Just guessing on the location of the actual bit he hit.
As for the PBs strolling across the runway in a leisurely fashion with 70 tons of certain death heading for them at .2 Mach, no change....
