Everyone does a top 10 list. This year, we decided to switch it up, going with the top six Ideas@Innovations stories of 2012.
No. 6: The X-51A Waverider In this July 17, 2009, photo provided by the U.S. Air Force, an X-51A WaveRider hypersonic flight test vehicle is uploaded to an Air Force Flight Test Center B-52 for fit testing at Edwards Air Force Base. Our live coverage of the craft’s failed test flight in August was the sixth most-popular innovations story of the year. It was later announced that the failure was likely due to an early fin release.
