In 2013 Boeing knew the handwriting on the wall for its 747-8 program. It was spiraling downward and would have remnant aircraft orders by 2020. Currently it is taking a production step downward where it will go to about one a month. The 747-8F program received a note from management that four were cancelled by Japan Airlines due to consideration for its own needs for freight traffic. The freight segment is Boeing's most robust order engine for the 747.
This brings us to the 777-9X where in a few years since its announcement in 2013, it has again made year 2013 stick out, where over 300 hundred of the 777X types has been ordered, matching the venerable A-380 with its 10 year order book in only two years. Only fifty -Five A-380 have been ordered since 2013.
The 400 million dollar aircraft has set its production anchor with a design freeze and parts making has started for the first of many aircraft rolling forward. Its wing plant is a shell, but rapidly reaching its construction climax. The program progress has reported its progress wheel is turning "oh so slowly, but proceeding oh so finely".
