[*]The only planes in production at Long Beach at this time are the 717 and C-17.
[*]Freighters are no longer in production at Long Beach.
[*]The MD-11, ship number 646 you saw was sitting on the West Ramp waiting to be painted. No additional MD-11s are scheduled for production in Long Beach.
[*]During various stages of production the MD-11 rests on hydraulic jacks until the landing gear is installed. This all occurs indoors. MD-11s never sit outside without landing gear.
[*]No more MD-90s being produced in Long Beach. The last MD-90 "went over the fence" in January 2000.
