The 2016 games will involve roughly 30 million items, everything from condoms to firearms, with most marshaled from around the world and sent to Brazil on 6,000 cargo containers arriving by sea, air, and ground. About 70 percent of the imports came via container ship and 25 percent by air, with the rest traveling on trucks, said Fernando Cotrim, logistics director for the Rio games. From China, for example, came the 40,000 beds and 40,000 mattresses for an Olympics Village that has already drawn complaints from Australian competitors about the plumbing, and the smell.
