This is what I thought but Sterling did some hunting around and produced some numbers that I checked. Now I'm not sure of my maths but is seems to be the case that an object can leave the earth and hit the moon with only its escape velocity. At that speed the impact prssures are not enough to vapourise the impactor so it is possible to find fragments of terrestrial meteorite on the moon, in theory
