SpaceX engineers will be reviewing the data in order to learn more about what happened during the Falcon 9 flight. One of the unique features of Falcon 9 is the large amounts of data that come on separate telemetry streams from the first and the second stage. This will bring an end to the live webcast for today. Please check our website spacex.com, and our social media pages, where we will be providing you with more information as it becomes available. Thanks for joining us today."]);
