The role of shape-dependent flight stability in the origin of oriented meteorites

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Motivated by the conical shape of so-called oriented meteorites, we assess experimentally how the flight dynamics and postural stability of a body moving through a fluid depend on its shape.
