I don't disbelieve you, but again - Official Secrets Act. I doubt any of the wintering over scientists had a strong urge to end up on Robben Island for telling someone about the time that they were asked to take a short holiday and not ask too many questions.

Also, the fact that the overwintering teams are all listed as ending their time there in September strongly correlates to the date of the Vela Incident. So entirely plausible to send the winter team home a few days early and delay the the summer team.

No the schedule is March to April, with one month of takeover. Only the first few teams had different schedules. More plausible is that the blast was too far away and small to be observed from the island.

Ah my bad.
