saw a Korean Air 747 freighter being assembled. Only cost $5
Thats a bl00dy cheap 747!!!
Gulfstream - I did not find any way to visit there or the Boeing C15 Factory at Long Beach
I dont think you can visit the C17 factory at LGB, not surprising I guess as they are military. The flight school I used was based opposite the factory and used to see them doing run ups, tests, etc and then about once a week you would see them depart - very impressive!!!
