Did the Mayans Fly Airplanes?
Another great mystery that has caused many researchers to scratch their heads, are a group of 1,000-year-old gold pendants which have been unearthed within the Mayan ruins. These pendants measure just 150mm x 125mm in dimension, but they resemble objects that look almost exactly like modern-day airplanes. Some people debate the possibilities that these pendants are actually supposed to be flying insects or animals, but others bring up evidence that seems to prove that this is not the case. Airplanes, you see, require a part called a “vertical stabilizer”, which all of these pendants happen to feature, yet not a single animal on earth possesses. The question that remains is, “Could these aircraft actually fly?”
Thanks to 3D printing, we have found out. A group of researchers a the Tongji University College of Aerospace Engineering and Applied Mechanics, decided to test the feasibility of flying these aircraft, by utilizing a combination of 3D printing and laser cutting.
