Airbus A330
It has a new front landing gear system. Normally the A330-200 points slightly downwards when it is on the ground. This is good because the pilots can see the ground better but it makes loading the cargo harder. With this new gear, the aircraft sits straight so it is easier to load the cargo. It works by making the point where the plane attaches to the gear lower. This means that the nose has a bubble on the bottom to make sure the gear fits properly.
