I was browsing a website for a 747SP seating map and I stumbled upon some data for older aircraft range with max seating. The 747-200 in-game is listed at 7550mi, but the website shows 4880 nmi which translates to 5616 miles. The Lockheed L-1011-500 TriStar has a range of 5345 nmi, which translates to 6150nmi. The DC-10-30 range is 4604nmi, which translates to 5298 miles.
I've written down here all the incorrect ranges I've found.
