you mean he did a barrel roll? the airplane stopped at end of rwy 15, right on touchdown zone rwy 33, without seeing the signs on the rwy we cannot say what it did but 360 degrees in a 46mt wide rwy it is possible only at 15kts and if not, he went out of rwy...so anybody saw sign of grass incursion? that is what they initially reported anyways....maybe deeper down that was truth in it.
