I don't quite follow this. All the impacts should be in roughly the same
lattitude and wouldn't necessarily be 180 degrees around the globe, either.
Take a look at the work done by Bill Bottke, formerly of Cornell.
BTW, Bottke is has just joined the Southwest Research Institute in Boulder,
The examples all show chains of impact craters. SL-9 was a bit odd because
the spacing coincedentally made the impacts occur about once per Jovian day,
but they were all in about the same lattitude and not antipodal.
Yesterday I could not spell gernulest. Today I are one.
