Its only Wednesday and its already shaping up to be a week of extremes. Yesterday, I went flying an airplane that was built in the 1960's with 1930's technology. Its a Belanca Citabria, a plane with a tailwheel and made of a combination of metal tubes and wood and covered in fabric. Quite a technology throw-back. Today, we are getting ready to hit the other end of the spectrum. We are scheduled to experience one of the coolest new technologies, the 4D ultrasound. I'll be posting some of the fruits of this as soon as I can get them converted to a format that will be viewable online.
