A model is proposed for the 5 March 1979 $\ensuremath{\gamma}$-ray transient. A small lump of strange matter, previously ejected from a supernova explosion, struck a slowly rotating strange star. This resulted in a high-intensity flash of radiation from a hot spot produced by the impact. The high-intensity radiation blew open a crater in the crust; the energy released as this crater refilled was responsible for the longer-duration, lower-intensity phase. The 8-s modulation is due to the rotation of the star. A plausible scenario for the production of this event is discussed.
