"Cal told me about a subsequent change that he developed that could offer some interesting properties particularly for deep descent. It would allow vertical diving with a head up attitude."

Holy cow! I haven't had my hands on one for thirty years and I had the mod figured out before I finished the sentence, I think. Don't know about steering though. I only spent 15-20 minutes talking to that brilliant man but, like the other few geniuses I met, I wish I had recorded their words. I also made an 'artist's concept' sketch of a head shield about 20 years ago. The basic idea came from a bicycle shield but it looks a lot like his.

I never thought about flying in water until I saw your pictures. Just about 8 years ago, I landed at Honolulu, parked at the gate and never touched the contols of an airplane again. That glide from 110-200 feet last Sunday felt just as good but I have to admit that the visibility from the 747 was a lot better and at Rio or the old Hong Kong airport, a lot more exciting too.
