We trawled back through the subband statistics (SST) data to find the exact instant that LBA aerial #L34 was destroyed. The critical moment seemed to be around 18:50:20 UTC.
As can be seen, there is a possible preliminary event some 12 seconds earlier. Not sure what this could have been. Flying debris, perhaps?
In any case, this was the point when we lost aerial #L34, which probably was due to flying debris from tile #H75.
