A South African man has done the stuff of every child's dreams after floating from Robben Island to Cape Town attached to 160 helium balloons.
The daredevil travelled 3.7 miles across the Atlantic and had to control his landing by popping balloons.
All did not go to plan however and a change in wind direction threw Silver-Vallance off course, reports Times Live.
He said: "I was going up...then I started coming down again, that's when it got hairy again.
"Would we do it again? Probably not."
Silver-Vallance landed in the sea not far from his intended target and was picked up by a coastguard boat.
