BLT Research Team

The BLT Research Team Inc., founded in the early 1990s in the United States, is a civilian organization focused on investigating physical anomalies in crop circles, including plant and soil changes. Named after biophysicist W.C. Levengood, Nancy Talbott (director), and John Burke (funding), it conducted lab analyses claiming expulsion cavities, germination alterations, and magnetic particles as evidence of non-hoaxed formations possibly linked to UFOs or electromagnetic forces. Notable for reports on iron spheres and microwave effects, its findings faced criticism for methodological flaws and lack of peer review, failing to gain scientific acceptance amid crop circle hoaxes revealed in 1991. The group appears inactive today.
