THE final moments before two skydivers jumped to their deaths in a tragic accident have been captured on video by another parachutist who left the plane seconds before them.

Dustin Leonard filmed the men — an instructor with thousands of hours of parachuting experience and a Singaporean man in his 20s strapped to him for a tandem jump — as they lined up at the aircraft’s door.

The GoPro camera footage captures the high spirits on the flight with the instructor, aged in his 60s, smiling in anticipation.

A minute later both men were dead after their chute failed to open and they landed in the driveway of a rural home at Wilton, about 85km south-west of Sydney, about 2pm.

“I think it’s just tragic. It’s just a fluke accident,” said Mr Leonard, CEO of Hero Condoms, a company which donates condoms to developing countries fighting the spread of HIV/AIDS.

They were the only tandem skydivers on the flight, “and they were the last to jump”, Mr Leonard said.

The instructor killed in a tandem skydiving lesson alongside his student was extremely experienced, having made more than 10,000 jumps in his 30-year career, AAP reported today.

Investigators are still trying to find out what went wrong in the jump that has been described as “not especially challenging”.

“This is the first fatality involving a first orientation tandem skydive the company has had in over 40 years of operation and is an extremely rare incident,” the Sydney Skydivers centre said on its Facebook page on Sunday.

“The particular skydive the two men were undertaking was not especially challenging for a highly experienced instructor, who had done nearly 10,000 skydives and had nearly 30 years experience in the sport,” it said.

All skydives were cancelled today out of respect for the two men.

“Our sympathies go out to the families and friends of both men as well as those in our skydiving community,” the Sydney Skydivers post said.

“We are doing our best to ensure any support is provided to our staff, skydivers and those involved at the scene itself.”

Colombian tourist Catalina Granados jumped minutes before the fatal accident happened.

She was with her boyfriend, who booked the skydive as a gift for the couple to experience together.

“I couldn’t believe (it),” she told AAP today.

Mr Leonard was similarly surprised when he landed and walked back to the parachute company office to sign up for a second jump scheduled for the afternoon.

“We got notified that some guys might have landed far away,” he said.

“I don’t think anyone knew something bad had happened.”

Police and emergency services were called by a resident who saw the victims hit the ground.

A seven-year-old girl who was one of several children at the home had to be counselled after seeing the bodies shortly after the accident.

The Sydney-based instructor and the other man in his 20s, in Australia on a work visa, were jumping with well-known company Sydney Skydivers.

Chase Stephenson, who co-owns the property, said his daughter had been distressed at the sight of the bodies.

Mr Stephenson said: “She has seen the aftermath. She hasn’t seen them hit the ground but she is pretty traumatised. It’s a shocking thing for a young girl. She’s very shaken up by it and has spoken to a counsellor.”

Mr Stephenson said he was told of the incident by his sister and mother, who live at the property.

“I’ve been told they landed in the driveway. So there’s no real nice way to put it,” he said. “It’s not the sort of thing you expect to happen.”

He said his five-year-old nephew also saw the bodies and his two-year-old niece was there but was unaware of what had occurred.

Sydney Skydivers owner Phil Onis said his employee had 20 years ­experience and that his skydivers normally had two parachutes.

“We are keen to get in there and find out what happened,” he said.

Mr Leonard said: “There are risks with solo jumps but there should be no risk with a tandem jump. Skydiving, statistically, is almost safer than driving a car.”
