The first experiment that obtained some hints in favor of neutrino oscillation was a solar neutrino search carried out in the Homestake mine in the early â70. Since the Homestake mine only detected electron-neutrinos and not the other two flavors, it missed observing the neutrinos that had changed their identities by the time they reach Earth.
