"[He was] very lucky he didn't land in the water because it could've been a whole different kettle of fish," said Driessen.
He said the hang glider would have struggled to get out of his gear in time and could have easily drowned.
"Luckily he was in the sand dunes and easy to spot from the air."
But Driessen said the rescue was "was quite hard, it was really windy and there was sand blowing everywhere."
The crewman, doctor and paramedic treated him and the helicopter departed the scene at 2.30pm and landed at the hospital 25 minutes later.
Driessen said the man had hang glided before but the conditions were gustier than he was used to.
He said the victim may need an operation to treat the injuries.
