Interesting isn't it, the data I mean. I will look on my web site and see if
I have most of them. Will incorporate in the big Cd list along with the CdA
numbers already there. Dan mentioned in a previous post that it was useful
to have a wind tunnel at your disposal to figure these things out. Sure is!
But if you are like me, I cannot afford the use of a large tunnel for
anything. And if that is a public institution then is that what my tax
dollars are going for? I stand behind my math and am looking forward to
getting some data from you all this summer.
