Grizz, I completely agree. BJ-ENG's post is in my view required reading. Understanding the difference between aircraft structures impacting solid ground and water is, I think, important to understanding what the photographs have shown us in terms of the "stopping" capacity of water vs level ground, (ie, Tripoli vs what we see here thus far). I think how BJ-ENG's post describes this difference has added a great deal to the thread's knowledge.
