I do not believe it will happen. "How do I write a letter to tell my wife I died because the rocket blew up, without sounding like I doubted the glorious Soviet rocket?"
I don't know if an ~85% success rate is actually good, but given that this was the very early days of the exploration of space, I'm willing to accept that it's not bad.
