Working for Boeing has some percs I suppose I have had the honor of visiting the C-17 plant in Long Beach have seen F-18s and F15s being built in St Louis,Warthogs,C5s,F16s,F111,B1s,F14s,F4s and C141s in AZ. and MD11 MD 80s/90s,777,767,757,747 in Long beach and Everett (They drive full size trucks in that Plant just to get around) I have not been in any of the composite plane areas (didn't have security clearance) but from all the aircraft I have been around they all have one thing in common they are really not that spectacular during the build process but they sure look cool when there done.
