The strength of modern airframes, given what that aircraft did, is to be commended. I haven't see such a thing since the Mohawk/Piedmont (stand to be corrected on the company) 1-11 left the runway, went across a road, between two buildings, and, despite having lost both wings, the pax and crew walked away. This incident was used as training for Bcal crews when doing their conversion, to the 1-11 in Pittsburgh, with regard to the strength of the airframe.
If aircraft had Ncap ratings (safety ratings to our US contributors) then this one would have got 5 stars, at least.
