I am not sure that this is a valid test case. Although the neutrinos 
were detected 3hrs prior to the light detection from SN 1987A, with some 
possible detection 5hrs prior to that at LVD also under the alps, the 
detectors were detecting electron neutrinos which is not the same 
flavour as those in the OPERA experiment.  As these beasts oscillate 
between the different flavours I think it could not be excluded that the 
muon neutrinos,  which, if I understand correctly, the OPERA detectors 
are trapping, had already passed by.
