Three years after its launch Swift has successfully localized and observed a few hundred GRBs. Its well-known speed in slewing to the source has led to great discoveries such as the flaring activities in early X-ray afterglows and the detection of Short GRB afterglows. In a few cases, mainly Short GRBs or late observations, XRT did not detect any emission. However, for six Long GRBs XRT could not measure any X-afterglow either, even as early as 100 s after the BAT trigger. In this paper we present a study of these unusual events. We analyse their peculiar behaviour in the Gamma and X-ray bands and discuss their singular origin.
