As of today, only ${\\sim}\\,6\\%$ of meteorite falls have been firmly linked to their sources (Moon, Mars, and asteroid (4) Vesta [4-6]). Here, we show that ${\\sim}\\,70\\%$ of meteorites originate from three recent breakups of $D > 30\\,{\\rm km}$ asteroids that occurred 5.8, 7.5 and less than ${\\sim}\\,40$ million years ago.
