Twin teenage sisters who have landed high-flying jobs will be putting their skills on display at Lowestoft's Air Festival next week.
Twins Libby and Poppy Dover will wingwalk at Lowestoft air show
The 19-year-olds will be performing aerobatics on identical 1940s Boeing Stearman biplanes on 28 and 29 July.
"Wingwalking is the best roller coaster ride in the world," said Libby Dover.
"Poppy and I are so close and it is utterly amazing for us to have landed a job where we can work side by side, even if it is 500ft in the air!"
Libby has taken up wingwalking during a gap year after A-levels.
Art student Poppy said the most exhilarating part was climbing around the aircraft in flight.
"We have learned to climb from the open cockpit of the biplane up onto the wing against 100mph wind pressure and for our final flypast we will stand in a position between the cockpit and the wing to wave at the crowd during a knife-edge pass."
The air show, which was under threat two years ago, was saved by a package of measures agreed after civic leaders insisted it had to go on.
The show attracts 350,000 visitors and pumps more than £11m into the region's economy.
