Question

whats beneath your plane?
as shane loeffler, a geology student at the university of minnesota, was flying home from europe, he looked down at the landscape and began to wonder what he was flying over. he realized that a plane flight would be a good opportunity for people to learn about the geological features of the earth below them. as a result of this experience, with a grant from the national science foundation, he created a free app called flyover country. the app provides users with information on natural formations, man - made features like dams, and even where fossils can be found. the features are pinpointed on a map that corresponds to the landscape below the plane.
