Just in case you have been off of the planet for a year or two, Gabby was the U.S. Congress Member who was shot in the head in Arizona. Mark Kelly is her husband. However, he has had a very illustrious career himself. Mr.Kelly has been with NASA for many years. He is also a Gulf War veteran, having flown a number of bombing missions over Iraq. I actually know a lot more about his career than you might think I shoud, and I didn't look him up on Wikipedia.
I had the good fortune to hear Mark Kelly speak in May of this year. He was the commencement speaker for my son's graduation at SIU Carbondale. His presentation was phenomenal. You could hear a pin drop in the area during his entire presentation - even with the all the little ones in attendance.
Now add in his wife who must have the courage and perseverance of a Saint and this should be a knock your socks off wife your eyes presentation.
Hope to see you there
