Re: NW DC-10-40 vs DC-10-30

Did NW at any time operate the few late build -30ERs on select “longer” DC-10 runs? Presumably, even if the trim tank was removed, the higher MGTOW would have still been an advantage over an ex-Swissair from 1973, per se. N226NW comes to mind, ironically an ex-Swissair from 1980.

Re: Why didn’t 3 engine planes push out 4 engine planes like 2 engines did?

In the 1970s, available Trijets didn't have the range or the size of the 747-200. The only large Trijet that came afterwards was the MD-11, made by a cash-strapped company and had a 20 year old wing. Pure speculation but the MD-11 would have to be 10% larger (A333/772 size) and flown an hour further...

The Airbus A220 has exposed gears and it's a clean-sheet design. I'm guessing the weight penalty as a percentage of gross aircraft weight is larger for smaller aircraft.

Remember, it's not only the doors, but there's also the associated hydraulics and machinery to open/close them.
