Horror as 33-year-old British base jumper plunges to his death from a tower block in Thailand after his parachute fails to open

A British base jumper has died after his parachute failed to open as he plunged to the ground from a tower block in Thailand.

Nathy Odinson, 33, from Huntingdon, Cambridgeshire, illegally climbed to the top of the 29th floor of an apartment building in the coastal city of Pattaya on Saturday evening before falling.

Horrifying footage shows the tattooed daredevil counting down 'three, two, one, goodbye' before leaping into the night sky – only to enter a deadly downward spiral as the tiny parachute floats through the air.

You then hear Mr. Odinson land in a tree before hitting the ground with a sickening thud. Paramedics pronounced him dead at the scene.

Tourist police in Pattaya were informed of the accident at 7:30 p.m. and rushed to the apartment building in Tambon Na Klua in Chonburi province's Bang Lamung district and found Odinson's body on the ground.

Terrifying images show the brutal aftermath of the fall

Tourist police in Pattaya were informed of the accident at 7:30 PM and rushed to the apartment building to find Odinson's body on the ground

A round blue parachute was found on his body, which had not fully deployed.

Traumatized security guard Kanet Chansong, 33, said: “I heard the sound of the tree and I thought it was a fallen branch hitting the ground.

“A woman was screaming, so I walked over and realized it was a person. They were dead. I saw that they had jumped out of the building.'

In the video, Mr Odinson asks the person recording him from the other side of a security wall if the red light on his helmet camera is flashing to indicate recording is taking place. When he realizes no recording has been made, Nathy takes off his helmet and presses the button before briefly checking his parachute.

His friend, a Thai resident, shouts 'oh f***' when he hears Mr Odinson hit the ground. Shortly afterwards the emergency services were called.

Staff at the Lumpini Ville Naklua apartment checked CCTV footage and saw that Mr Odinson and a friend had parked outside and then waited for a while when it was quiet before sneaking into the building.

They then illegally entered the roof of the building, with Mr Odison clambering over a small concrete wall on the roof of the building to reach the edge.

The security guard said he had already jumped out of the building several times, posing a risk to pedestrians walking underneath.

He added: “They were making video content for social media. They had done this before and knew it wasn't allowed.'

Police and paramedics arrived on the scene shortly after 7:30 PM local time. However, Mr Odinson could not be saved.

Police Lieutenant Kamolporn Nadee, deputy investigating officer at Bang Lamung District Police Station, said there were no initial signs that Mr Odinson had been attacked.

The police officer said: “The parachute used by the deceased to jump did not function properly and was not centered as expected. He was in a terrible condition when we arrived.

“The friend who recorded the video of him jumping was questioned and the video was examined as evidence.

'Forensic detectives are investigating the matter further. They're examining the parachute.'

Mr Odinson was a real daredevil and had performed skydives and base jumps all over the world. He ran an “aerial photography” business and took clients on private skydives.
