Observations of high-velocity, weakly shocked ejecta from experimental impacts

The results of a cratering experiment on the ejecta from different regions around the site of a meteorite impact are presented. The material recovered was found to be high-velocity and weakly shocked, which supports the theory that the meteorites were planetary in origin.
