We report on the detection of four rotating massive disks in two regions ofhigh-mass star formation. The disks are perpendicular to known bipolar outflowsand turn out to be unstable but long lived. We infer that accretion onto theembedded (proto)stars must proceed through the disks with rates of ~10E-2Msun/yr.Comment: 11 pages, 2 figures, 1 table; accepted for publication by ApJ
