An interesting fact that happened a long time ago...the Vela incident!
Back in the late seventies, the Vela satellite recorded a flash with a double pulse signature, this being characteristic of a nuclear detonation located somewhere between South Africa and Antarctica. To this day the mystery remains unanswered, who could have been responsible for this? The most likely answer was a covert collaboration between South Africa and Israel.
The picture I have created is based on speculation and comprises of various elements surrounding this interesting story. Centre-stage is the nuclear cloud with Bouvet Island seen through the sea spray in the distance. An interesting addition and something that all conspirators missed, a Daphne class submarine loitering in the vicinity of the blast, possibly the delivery vehicle and used to validate and record the event!
