Richard Branson will mourn, but won't be deterred

(CNN) – Virgin Group founder Richard Branson reacted to the deadly explosion of Virgin Galactic's SpaceShipTwo test flight Friday, sending a tweet that read: "Thoughts with all @virgingalactic & Scaled, thanks for all your messages of support. I'm flying to Mojave immediately to be with the team."

One person died and another was injured in the explosion, which the company described as a "serious anomaly."

And while Branson will mourn the outcome of Friday's test flight, he will not be deterred.
