Slovenian adventurer and environmentalist Matevz Lenarcic on Sunday became the first person to fly an ultra-light plane from Europe to America and back over the North Pole, as he landed in Ljubljana after an epic voyage.

“I’ve had more trouble than I had expected, and that prolonged the expedition but what matters is that me and the plane have arrived safely,” the 54-year-old told a crowd of well-wishers.

But his month-long journey was not all plain sailing.

The trained biologist had to make an unscheduled stop in Saint-Nazaire, northwestern France, due to weather conditions and an Irish airport did not have the type of fuel required for his aircraft.

“I’ve had many unexpected events. That is why this trip has taken 14 days longer than initially planned,” Lenarcic said Thursday on arrival at Saint-Nazaire.

The plane was equipped to measure air pollution over the North Pole — a hot-spot for global warming — and Lenarcic said all measurements had gone as planned.
