this is good package of information

Bery informative coarse

Great explanation

video and presentation was clear and informative,

Very interesting. I really wanted to understand this information, and it was explained real nice and simple; even for someone like myself to understand.

Thanks Martha, good explanation. For now I'll stick with sub Mach numbers as I learn. Use to drive cars on the Autobahn at 283km/h (175mph) but that was 40 years ago in a M5 BMW. ;-)
