My thoughts are with you and on angels wings to the lost astronauts and their families.
One of my employees husband trained them. He knew all of these people killed today. Every so often (before 9/11) I used to go over to NASA and he took me through all the simulators. We had the run of the place. One time Glenn was there.
My prayers are with the people lost today and their families. And all the "taggers*" that work to make a very complicated system work as well as it has for many years.
Like the WTC, we will build newer spacecraft. It's our way. We are Americans. Nothing will stop us.
*We call the local engineers, etc. that we see all over "taggers" because of all the security badges usually hanging off them.
