Welcome back to the our channel for a discussion about how landing gear for massive Civilian and Military Planes is designed, constructed, and maintained. I worked just north of a C5 base for years. It always amazed me how quiet these behemoths were. They would fly over at just a couple hundred feet. Never heard them till after they flew over. I remember when I was a kid long time ago at my grandfather's farm one day we heard a story one guy from our village bought an old landing gear at junk yard and he mounted the tyres on his tractor trailer , it took five men to set one tire for a whole day. He said this will last forever and he took a hammer and a knail try to puncture the tyre and nothing happens. As mentioned earlier by Bill Luce, your facts need to be revised. The landing gears on the A380 were in fact design by two different companies. Safran designed the Nose Landing Gear and it's components, nothing else. United Technologies Aerospace Systems (formerly Goodrich Aerospace), turned Collins, now Raytheon Technologies designed and manufactured the mains; the body gears and wing gears.
