This is the dramatic moment a helicopter crashed near a Mount Everest base camp during a rescue mission in Nepal.

Footage shows the aircraft skidding on the snow as it attempted to land at the Lobuche helipad on Wednesday morning, October 29, around  7:52 am local time.

Authorities said the chopper, operated by Altitude Air Pvt Ltd, took off from Lukla Airport at 7:41 am.

A report from the Aviation Safety Network stated: 'Upon landing at Lobuche Helipad, Solukhumbu, on a snowy mountain, a Eurocopter AS 350B3e Ecureuil (Airbus H125) toppled over and ended up on its side.

'The pilot was uninjured, and the helicopter received substantial damage. The helicopter was due to rescue stranded foreign tourists in Lobuche.'

Deputy Superintendent of Police Manojit Kunwar, head of the District Police Office in Solukhumbu, confirmed that Captain Vivek Khadka, the sole occupant of the helicopter, emerged unscathed.

He was later airlifted back to Lukla by a Kailash Air helicopter.

Police added that the aircraft did not catch fire, but slid and toppled on the snow-covered helipad.

The Mount Everest region has been blanketed in snow since Monday, as a cyclone from the Bay of Bengal swept across northern India.

Helicopters had been flying rescue missions since early Wednesday morning to evacuate stranded trekkers in the Khumbu region due to the heavy snowfall.
