I remember the Challenger disaster well, I was in school when it happened. That was such a sad event, and the later loss of the Columbia. I still remember watching the first Columbia launch on TV, it was early enough that I hadn't headed of the school yet.

Dream Chaser looks to be an awesome creation. I hope it's successful, we desperately need a way to get supplies into orbit especially if the Russians completely pull out of the ISS as threatened over the Ukraine war.

Keep up the good work, you are always finding interesting stuff. I love it!
