According to The Sun, the Summit Air plane was taking off from Tenzing-Hillary Airport in Lukla, north-eastern Nepal, when it crashed into the helicopter which was stationary on a helipad.

The plane, operated by Summit Air, was not carrying passengers as it was trying to leave what is considered to be one of the world's most risky airports due to the shortness of its runway and its location surrounded by mountains.
