We all know about the danger of space flight,
these womans and mans paved the way for the whole mankind,
real pioneers.

I was outside when Columbia went over Texas. I was standing in my driveway when a dollop of melted metal hit my roof. I contacted NASA about it. They never came to get it, so I preserved it in a block of acrylic and mounted it.
<S> to all them.

they risking there lifes for our all future.
