If we are talking about the same event, it was a tire failure, caused structural damage to the engine and tail area.
Mike, #1 MD90 sim is flying nicely and is approved for use by the PCA. Actually flew it a couple of days ago, unfortunately its not a nice as the B777 sim sitting beside it, nor is it approved for FAA type ratings as the FAA are too scared to enter Saudi Arabia.
