Like anyone born on or before the 70s, I remember watching the Challenger explosion on live TV. I was just a kid, yet I still remember hearing about the O-ring failure that led to the tragedy. What I didn't know, was the true story about Roger Boisjoly & co. trying to stop the launch the night before, knowing full well what would happen. It's a very interesting, albeit sad story. If you enjoy movies about true life heroes, you will likely enjoy this movie.
