ADVENTURER James Ketchell is set to land back in the UK today (Sunday) after completing a "mind-blowing" challenge to become the first person to fly solo around the world in an open-cockpit gyrocopter.

The 37-year-old from Basingstoke set off from Popham airfield on March 31 in the small aircraft which is similar to the one seen in the James Bond movie You Only Live Twice.

The MAGNI M16C gyrocopter travels at 70 knots, with a range of just 700 nautical miles.

His 24,000 nautical mile 175-day journey took him across Europe, Russia, Canada, the US and the Atlantic Ocean heading to Greenland and Iceland, before his final staging post on the Danish Faroe Islands.

Mr Ketchell told PA: "It's all a massive blur to be honest, the fact that I have literally flown around the world, it hasn't sunk in, it's probably going to take quite a while to, it feels really good, it's been magical.

"The highlights undoubtedly have been the people I have met, I will be paying forward-favours for the rest of my life and it doesn't matter what country I was in, what language they speak, people have been so helpful, people have been amazing."

He added: "As soon as you get up in that little gyro and you start flying over remote Russia, Siberia, Greenland, it blows your mind just how big this planet it is and you can feel quite small.

"The wildlife has been incredible, I have seen massive black bears running around in Siberia, seen whales, you name it.

"I have been flying 20ft off the ground, it was just incredible and there is no other aircraft that you can do that, it's magical, you can really immerse yourself in the surroundings, you can smell the water, the seaweed on the beach, if you could bottle that experience you would make a fortune."

He said the greatest challenge had been the levels of concentration required while flying for many hours.

He said: "This project is hugely mental, you can never relax, you are always on edge thinking of the next flight, always looking at the weather.

"What people don't realise is that the levels of concentration are really high when you are flying, it's a like flying a motorbike in the sky, you are fully exposed to the weather because it has no cockpit, it's mentally draining, it's a cumulative build-up of fatigue, in that sense this is the hardest thing I have undertaken."

The circumnavigation follows his previous "ultimate global triathlon" which saw him row across the Atlantic Ocean in 2010, climb Everest in 2011 and cycle 28,969 km around the world in 2013.

During the trip, Mr Ketchell, a UK Scouting ambassador, set himself the goal to speak at a school in every country he visited to help motivate youngsters.

Describing visits to schools in Siberia, he said: "The look on these kids' faces, big eyes staring at me with their mouths open while I was telling these stories as they were being translated was a really magical feeling and all the stresses drifted away, this is what this is all about."

Mr Ketchell described how he spent his teenage years depressed and lacking in confidence, and how a serious motorcycle accident led him to turn his life around.

He said: "With the birth of social media, teenagers now are frightened to do anything in case they get hung, drawn and quartered because they are worried about their image, I try to get my message out that 'Don't worry about anyone else and get out there and do your thing and your life will become free'."
