He managed to fly 15.5 miles across South Africa, reaching heights of up to 8,000 feet.
"It's going to be a three-day, long-distance, floating adventure under party balloons on a chair", he says in a YouTube video.
Morgan believes Botswana was the ideal location for his bold journey.
"We will have to avoid areas with lots of spiky bushes though", Mr Morgan said.
"The problem was finding a good weather window and it was hard to protect the balloons as they kept bursting", Morgan told to BBC. The team reportedly had just enough helium left for a final attempt. He used almost 100 giant helium balloons, which used a total of 144m3 in helium (that's a lot).
Mr Morgan, a founding member of the Bristol-based League of Adventurists, whose aim is to "make the world less boring", spent two days inflating his cluster of balloons.
On Monday, October 23, he strapped himself into a chair, surrounded by safety supplies, gave his teammate a handshake and was on his way.
Morgan admitted that he was feeling "somewhere between terrified and elated" as he rose into the air, risking his entire life to the support of helium balloons.
While Morgan describes the experience as "unbelievably cool", when it came time for him to come back down, "I had to keep my cool and start gradually cutting the balloons".
'There was a priest from South America who did it a few years ago and he went too high and didn't come back'.
In a stunt that looked fresh out of a Pixar movie, one man flew 8,300 feet (2530m) above ground lifted by nothing but helium balloons.
