Radar measurements confirm that the several hundred million individually orbiting West Ford dipoles reentered the lower atmosphere in precise accord with predictions. Calculations indicate that these tiny copper wires survived reentry and floated gently back to Earth; unfortunately,the probability of finding one is minuscule. Some dipole clusters remain in orbit but almost all should return to Earth within the next 2 years.
