San Antonio is believed to be one of three sites being considered by Boeing to build its revolutionary 777-X carbon fiber jet, now that machinists at Boeing's main facility in suburban Seattle have rejected a new contract, 1200 WOAI news reports.


  Boeing has not formally announced the facilities under consideration to do the work which was slated for Boeing's sprawling facility in Everett Washington, but a company official did say that 'no option is being taken off the table.'


  Several observers say San Antonio would be the best choice to build the plane, which is being touted for its lightness and fuel efficiency.  Boeing employees more than 5,000 people at its plant at a former Air Force hangar at Port San Antonio, the former Kelly Air Force Base.  Among the advantages cites for San Antonio in a Seattle Times analysis was an 'experience work force and eager state government.' 


  Texas voters earlier this month approved a change in the business tax which was believed to be in preparation for a possible move of 777-x work to San Antonio.  The new proposal will allow companies to hold onto airplane parts for a longer period of time before they have to pay taxes on the parts.


  The negative cited for San Antonio is a lack of 'port access' which would be useful to bring in large aircraft parts to the assembly site.


  Another leading location for Boeing's 777-x work is thought to be Long Beach California, where Boeing acquired a huge airplane manufacturing facility when it bought McDonnell Douglas in 1997.


  Other possible sites include Salt Lake City and a facility in Charleston South Carolina, both of which do extensive work on the Boeing 787 Dreamliner jet.


  Boeing says it may also build the 777-x in Washington State, although it says it has no plans to reopen negotiations with the machinists union.


  Emirates Airlines in Dubai is expected to place a large order for 777-x jets this weekend, meaning that work on the plane will have begin soon and be able to ramp up very quickly.
