The Yellow Cuban Balloons

The Yellow Cuban Balloons

The Cold War saw all kinds of weird stuff happening on both sides of the Iron Curtain, but one of the most perplexing obscure mysteries happened off the coast of Florida. In June of 1967, a Coast Guard trawler picked up a floating crate in the ocean that was stamped "Property Of U.S.S.R." and addressed to the "Institute of Mineral Resources of Cuba." Inside the box? Seven yellow balloons, inflated with an unknown gas and closed with black rubber stoppers. Scientists examined the contents but they revealed nothing but ordinary air. In the decades since, no explanation has ever come forward about what the purpose of the shipment was.
