Now that's a hard landing!!!
This was not a failure of the aircraft, this was to test the maximum impactQuote:

believe it was also used as the unducted fan tests at the end of her life. I
am not 100% sure about this being the same aircraft used as the unduced
fan test, but cool none the less. I would have loved to walk around the
aircraft after all the metal cooled down!
I was actually impressed at how the main gear held up. The nose gear seems to have collapsted and the structure forward of the tail also seems to have done well with little visible shock.
I was impressed with the main gear too!Quote:

(The unusual low down nose seems to be camera angle, the engines would be really pointing at the ground if the nose collapsed.)
The spot just behind the wings and mains was beefed up for the MD-80 because the desingers knew this was to be the most likley place for a break. In the old DC-9's, this was the first place that would fail shown in the picture of an old Eastern DC-9 here. Look like the designers over designed it for the MD-80.
DC-9 Weak point
