My father and I were almost exactly in the same space you were to see STS-75 go up. And I thought my reaction was due to the place and event and the feel of the pressure on my chest from the blast-off, but it's not just that.
It's from seeing a rocket with people from Earth leaving to go to work in space. When I watched your vid, I got all choked up again. Thanks and hope you get a chance to go back and see another launch. Good Vid!!
Think cosmic !!
