RA001 FLIGHT TESTING RESUMES The first 747 ever built, RA001, was back in the skies this week with the 777's Pratt engine attached for more flight testing. The PW4084 engine -- a later version of the same engine that was tested aboard RA001's left wing last year -- arrived from Pratt at Boeing Field last week for more ground and flight testing. The airplane took off Saturday for a check-out flight, and then traveled to Montana on Monday where five flight tests were conducted, including engine operating tests and installation tests. The airplane returned to Boeing Field Wednesday, at which time the engine was removed for return to Pratt. All tests were completed successfully.
