Alexander Polli, one of the world’s most celebrated and daring wingsuit pilots, has died after crashing into a tree during a flight.

The accident took place in the Couloir de l’Ensa mountainous area in Chamonix in the French Alps.

Mr Polli, 31, reached international fame after posting a video of himself flying through a small hole in a huge rock called the ‘Roca Forada’ in Montserrat, Spain.

Alexander Polli, 31, has died on a wingsuit jump in the French Alps after he hit a tree

Mr Polli is most famous for when he flew through a huge rock called the ‘Roca Forada’ in Montserrat, Spain

The video of this stunt has been viewed more than 13 million times showing his skill at 155 mph

The video, seen more than 13 million times, shows the skilled pilot in his wingsuit flying through the hole at 155 mph (250 kph).

His most recent flight ended tragically, however, as the daring jumper leapt from a height of 5,000 feet (1,500 meters) and smashed into a tree.

His friends quickly called the police who sent out a rescue team to save him.

Mr Polli was conscious when they arrived, but the gravity of his injuries meant the team was unable to keep him alive long enough to transport him to hospital.

A spokesperson for the mountain rescue team in Chamonix, identified only as Mercer, described the area as popular but dangerous. He said: 'It's a location where there are a lot of accidents.'

Mr Polli, who was born in Norway and brought-up in Italy, was a recognisable figure in the BASE jump and wingsuit world.

He also founded the YouTube channel for his flying group ‘Morals Arrivederci’ (Goodbye to Morals) where he shared videos of his flights and other amazing feats.

The description of the group reads: 'What does Morals Arrivederci mean? It means whatever you want it to mean! It is an extreme brand to motivate everyone to test their capabilities in this world. Breathe! Live! Never Give Up On Your Dreams!'

Despite his incredible feats, Mr Polli had admitted he was scared of heights. He said: 'To be quite honest, I am extremely scared of dying - and I am scared of heights.

'I never would have embarked on this kind of sport if I had had to be the first to do it.'
