I had no idea Challenger had people saying it shouldn’t go forward, and then trying to cover it up! I thought it was just a freak accident no one could have anticipated. I guess the cover up worked.


Integrity, wish there was more of it in the world.


Crazy, I just finished.Truth, Lies, and O-Rings a couple of weeks ago. Really fascinating book.


Wow, what a man. I feel honored to know this story and pass it on.
