On April 9, 2008, Boeing officially announced a fourth delay, shifting the maiden flight to the fourth quarter of 2008, and the initial deliveries to the third quarter of 2009. The announcement indicated the new schedule included extra time in the testing schedule to accommodate future unforseen delays.[62][1] In order to keep Boeing's latest schedule, the 787 must complete flight testing over three quarters, in line with the 9 month flight test campaign originally stated. In September 2007, after announcing delays, Mike Bair said that Boeing would keep the Certification Date using six flight-test 787s at a rate of 120 FT hours per month, higher than the 70-80 FT hours per month used in previous planes.[63] Boeing's previous major aircraft, the 777, took 11 months with nine aircraft flying 7000 FT Hours, partly to demonstrate 180 min-ETOPS, one of its main features.[64]
