- wnkrshm 5y agoInteresting and thanks for sharing, I also ran into another design that is maple-seed like in terms of aerodynamics. Sadly this is one of the cases where human ingenuity is misdirected and is still causing harm today: The BLU-43 Dragontooth mine [0][1] and the Soviet PFM-1 [2] which still are responsible for children losing limbs in Vietnam, Laos, Cambodia and Afghanistan. The BLU-43 came with a chemical deactivation mechanism but of course that failed in a subset of dispersed mines. The PFM-1 in Afghanistan came without a deactivation mechanism, the later PFM-1S had one.
