This is comparing one single safe landing to a crash landing. Does that gain us new insights? Not really. For that, we'd need the crash landing compared to the average landing, and also to other (safe and unsafe) extreme landings of the past.

And to get all Tufte of the graphics: Most of this is chart junk. The 3d view only serveres to hide information, and overlaying the paths (in 2d) would actually let us compare more accurately.

Average aircraft approach is a 3º glide slope. And usually all of them look exactly like that (only minor deviations due to the wind). If that chart is true is easy to see that they where high on the (non working) glidslope.
