Ok here is a question i cannot get answered right by people.
Reference for my question, is on page 74 in Terry Waddington's Mcdonnell Douglas Dc-10 book.
Question is: Aircraft 9Q-CLI of Air Zaire found in the picture at the top of the page of 74 has it's gear box doors open, but the weird thing is the main outer gear is hanging like a 767 gear. Why is that? In person, I have never seen such a thing on Dc-10's when the gear doors open. Also the way the gear box is design i know for a fact with the gear hanging as such, it would not even fit in the gear box. I have pictures in my personal collection, of gear doors opening or shutting with the gear extending or retracting, and no sign of the gear making a movement like this is visible.
Can someone clarify something here, or did i just miss something on the gear design?

What is your question? Are you asking if the picture attached (FedEx) is normal?. If so then yes it is. The gear is being retracted. The main "outer gear" is not hanging like a 767. What you are seeing is the Left Main Gear being stowed inboard and the Center Gear (it is a -30 aircraft) being stowed forward. The Center Gear hanging lower than the Left Main Gear makes it look like it is canted like a 767. It is just an illusion. If you look at it you will see all the wheels.

N737MC - I have a postcard of Swissair DC 10-30 HB-IHA in landing config., gear bay doors closed, with both main wing gear bogies canted like a 767's. I've wondered about this for years.
I've never seen another photo showing the same thing, and have never seen one like the photo for real.
It certainly isn't for the same reason as the 767 design, which is because the gear retracts not at 90 degrees to the centreline, but slightly forward. You're correct in that the gear would not enter the bays angled, the bogie would have to be at right angles to the leg.
This one's puzzled me for ages. Hope I'm on the verge of finally getting an answer!
