Thanks Bruce. Good point.

There is much about this graph we don't like. It is fine for illustrating a point to a technical audience so there are no qualms about it's scientific merit. But we are very concerned that it may be misleading/misinterpreted. To do this properly one would calculate these loads for all planes and present the highest for each design. Unfortunately, we don't have that much data.

We will probably pull it from the Web but use it in the presentation
