The cumulative distribution cf2>Ncf1>(cf2>dcf1>) of diameters of Earth-CrossingAsteroids (ECAs) derived by Poveda et al. ([Poveda et al., 1998], submitted) is used to estimatethe frequency of collisions of meteoroids with cars and with aircraft. The expected frequency ofcollisions of a car with a meteorite larger than 10 cm in diameter turns out to be one impact every16 years. This frequency is consistent with the known incidence of such events ([Lewis, 1996]).The expected frequency of collisions of a cruising airplane with a meteorite larger than 1 cm indiameter turns out to be one impact every 30 years. Such an impactor hitting an airplane at avelocity of several hundreds of meters per second could cause a serious accident. 1999 ElsevierScience Ltd.
