Joël Glenn Brenner is the woman who knew the copilot.
She also had a few not very kind words about Virgin Galactic... something like, "They sacrificed my friend for their program."
Here are four YouTube videos that I found by searching spaceship two and her name. One or more of them will be part of or the entire interview I heard Friday on CNN.
As you can see, the last one is titled "Brenner accuses Virgin of complicity in the death of experimental plane's pilot."
