A quartet of researchers at the University of British Columbia in Canada has calculated that the risk of one or more people being killed by uncontrolled rocket descents over the next decade is approximately 10%. In their paper published in the journal Nature Astronomy, Michael Byers, Ewan Wright, Aaron Boley and Cameron Byers, describe their study of casualty risk in the coming years due to rocket parts falling from the sky and what governments could do to make spaceflight safer for people on the ground.
