I just notice that I can't seem to order B747-400:
In the other hand B747-400D which would start delivery in 1990, a year after B747-400 delivery in 1989, is starting to be sold
I also goes to other World like (R2) and i notice that in 1987, you can already pre-order B747-400, a year before the pre-order for B747-400D even began, I just wondering if it's an error or the "pre-order" time in each world are different?
Thank you.
