spagliola, or may i call you spag
i was merely responding to the fact that a 747 would never have an ER varient because it only applies to twins thats all. a 747-200ER would never happen if it were a new aircraft today which is what you intimated in your post.
whatever you say goes with the rest as far as i'm concerned, i don't have the time to argue the toss over such a small point.
i've worked on every 747 varient going in one capacity or another over the last 13 years so please don't teach your granny to suck eggs on this one!
all the best.
