Quimbaya artifacts

The Quimbaya artifacts are several dozen golden objects, found in Colombia, made by the Quimbaya civilization, dated around 1000 CE, a few of which (the so-called Quimbaya airplanes) appear to resemble modern airplanes, and are therefore claimed to be out-of-place artifacts. The figurines, measuring 2 to 3 inches (5 to 7.5 cm) each, are described in mainstream archaeology as depicting birds, lizards, amphibians, and insects common in that region and period, some of them highly stylized, as in the Gold Museum, Bogotá.

In 1994, Germans Peter Belting and Conrad Lubbers created simplified radio-controlled scale models of these objects and showed that their models, which lack some convoluted features present in the real figurines, could fly.
