ZA004 has been engaged in long duration test flights over the last couple of days with two flights that lasted about 9 hours each. A source told me that these flights are performing steady state performance certification testing as well as laminar flow evaluations. ZA004 is in the air again today for another long duration test flight. The FAA is on board for these test flights. In other news, it is expected that ZA003 will be making the flight from Eglin Air Force Base to San Antonio for further hot condition environmental testing. It has successfully completed the testing at the McKinley Climatic Laboratory.
Lastly, Randy Tinseth put up a blog post addressing the temporary suspension of part deliveries into Everett. Boeing is delaying the shipping of the next two 787s (LN 23 and LN 24) due to parts shortages going into the suppliers.
