Yves Rossy, who calls himself "Jetman", is poised to make the first intercontinental flight powered by a jet-pack when he attempts to fly across the Strait of Gibraltar from North Africa to Europe on Wednesday.
The 50-year-old Swiss adventurer powered into the record books a year ago when he crossed the English Channel from Calais to Dover with a jet-propelled wing on his back.
He will now attempt the 23-mile crossing between Tangier in Morocco and Tarifa on the southwestern tip of Spain.
"It is going to be historic," Mr Rossy said ahead of the record attempt. "No one has ever done this before."
The daredevil, who also claims the nickname "Fusionman" - because he believes he combines the skills of man and bird - will leap from a plane on the African side of the Strait of Gibraltar and attempt to soar across north Atlantic waters at the mouth of the Mediterranean.
Using a four-cylinder jet pack and carbon fibre wings spanning over 8ft, he will jump out of a plane at 6,500 ft and cruise at 130 mph until he reaches the Spanish coast, when he will parachute to earth.
The journey, which is dependent on good weather, is expected to take less than fifteen minutes to complete.
Mr Rossy, who is a professional airline pilot, will be accompanied by a fleet of helicopters and aircraft to film the event, which will be broadcast live on the internet.
