The case of the MD11 doors is not a bug; it’s how it is in real life, as the MD11 doors open upwards, which makes the door disappear from the outside view of the aircraft. The same would apply to the comet (dh64)
I do realize that, which is why I was so excited to find out how they made that work. My expectation was that they’d model the galley of said doors and animate the doors opening in- and upwards. So it was quite a surprise to find that was not the truth.
Here’s a screenshot of the wheels on the 757, it’s on all variants of it (B752, B752F, B752CF and B753). If you look at the wheels on the left you can see they aren’t circles and more like an oval.
