The French Jetpack inventor and daredevil Franky Zapata reassured fans that he was "fine" after last being seen falling out of the air into lake Biscarosse on Saturday.
The inventor of the "Flyboard" - a jet propelled platform - was taking part in a demonstration at the small lake near Bordeaux when he began spinning out of control. The former jetski champion fell over 15 metres, in front of horrified crowds, reported Le Figaro.
"It was fortunate he fell into the water," tweeted one bystander who shared video of the incident. Emergency services were called but Zapata was quick to reassure the bystanders that he was not injured.
He took to social media shortly after the accident to thank those that rescued him from the lake.
Apparently in good humour, he tweeted that the accident was a "reminder that humans are not birds and if we are not at our best, gravity wins."
