By Lauren Gensler -Forbes - Even in the bloated-budget world of aerospace, $650 million is a lot of money. It's approximately the price of six of Boeing's workhorse 737s or, for the more militarily inclined, about the cost of seven F-35 stealth fighter jets. It's also the amount of money NASA and the Sierra Nevada Corp. spent developing the Dream Chaser, a reusable spacecraft designed to take astronauts into orbit. Sierra Nevada, which is based in Sparks, Nevada, and 100% owned by Eren Ozmen and her husband, Fatih, put in $300 million; NASA ponied up the other $350 million. The Dream Chaser's first free flight was in October 2013 when it was dropped 12,500 feet from a helicopter. The landing gear malfunctioned, and the vehicle skidded off the runway upon landing. A year later, NASA passed on Sierra Nevada's space plane and awarded the multibillion-dollar contracts to Boeing and SpaceX.
