Thanks for the comments.

You wouldn't believe how much time I spent on the first few slides of the
Lift / Drag lecture, the bit covering how a wing generates lift, to try to
make them benign with respect to controversy but still say something
useful and meaningful.

Kevin, when I get a chance I will go back and review the streamline and
force diagrams on pages 7 and 8 of the Lift / Drag lecture. It does look
like they might be slightly erroneous, but I just want to check back
through the literature and dig out some experimental results before I make
any changes.

Bildan, with regard to yaw generating roll via dihedral effects I do
actually say that in the slide. However the section on the effects of the
controls is going to get a rework at some point. It's the only point in
all three lectures where the audience without fail zones out on you and
looses interest. So I need to think up some way of making it more
interesting.

Richard
