Can't tell what the runway condition was at the time of the incident, but looks pretty clean afterwards. EXCEPT for the
end-of-runway (by Google Maps) maneuvering area to make the required one-eighty and backtrack. Sure as hell (my excuses to @Pontifex) that last bit of maneuvering concrete wasn't clean and tidy.
Maybe the poor guys didn't overrun as such, but ended up in the grass while misjudging the exact spot to make the U-turn.
