Hi Nige
Thanks for the explanation

When I mentioned 'beefed up'.. I was thinking more in line with say, a 747 and a 747F.. both of which look pretty much identical outside other than the obvious doors and lack of windows. That's an extreme example I know but I didn't want to say one was different from the other without knowing.. better no steer than a bum steer

As it happens with the 748, it's much like similar aircraft of the day.. including the Vanguard/Merchantman I'm reasonably au fait with, that is, the same basic aircraft with the same limitations across the board, modified to be one or the other

I spent some time looking at the 748 when the model was being made but have no real knowledge of the freighter.. it's almost as if it's new!
