Boeing Phantom Ray flies atop 747

Phantom Ray rode the 747 out of Lambert International Airport in St. Louis in preparation for being transported to the Dryden Flight Research Center in California. Boeing’s Phantom Works operation had been working on the UAV at the company’s St. Louis facility.This is the first time that an aircraft other than the space shuttle has flown on the SCA, according to Boeing.At Dryden, the 36-foot-long Phantom Ray will undergo ground tests and high-speed taxi tests. It has already undergone low-speed taxi tests at Lambert field. “It communicated with the ground control station, received its orders and made its way down the runway multiple times, allowing us to assess its performance and monitor the advanced systems on board,” Boeing said in a statement in mid-November.
