An American friend of mine, who is very disappointed with (a) the B777-9X airframe & (b) the GE-9X engine says :
-- arguably, the airframe is just a revamped tin-tube (Al-Li) stretch, of warmed up 25-30-year-old technology, with a new plastic wing ;
-- and the engines ("new" ?) are heavy, of "old-hat", 2-shaft architecture, whose performance appears likely to be substantially less-efficient than that of the RR -Trent-XWB engine, which GE considers as less modern than the GE-9X ("less modern" ? ) ;
-- RR is on the point of being able to bring into production the Advance, capable of extending the above-mentioned T-XWB engine's already existing lead over the GE-9X !
On December 16, 2003, Boeing announced that the 787 would be assembled in its factory in Everett, Washington .  Instead of conventionally building the aircraft from the ground up, final assembly employed 800 to 1,200 people to join completed subassemblies and to integrate systems.  Boeing assigned global subcontractors to do more assembly work, delivering completed subassemblies to Boeing for final assembly. This approach was intended to result in a leaner, simpler assembly line and lower inventory,  with pre-installed systems reducing final assembly time by three-quarters to three days.   Subcontractors had early difficulties procuring needed parts and finishing subassemblies on schedule, leaving remaining assembly work for Boeing to complete as "traveled work".   In 2010, Boeing considered in-house construction of the 787-9 tail; the tail of the 787-8 is made by Alenia.  The 787 was unprofitable for some subcontractors; Alenia's parent company, Finmeccanicam had a total loss of €750 million on the project by 2013. 
Hi Uresh - thanks for all your hard work to keep us updated. :) Question: Your spreadsheet shows LN16 is on the flightline with a delivery date of 7/2017. LN18 is in 45-12 Bay B with a delivery date of 3/17.
I'm just wondering why if LN18 is to be delivered 4 months earlier than LN16, that LN16 is on the flightline. Does this mean that LN16 will be delivered earlier than LN18 (and the delivery dates will change), that the delivery dates are correct and LN16 will just sit on the tarmac for an extra 4 months, or something else?
