For those who fall short of the summit, even the route back down is dangerous.
Since hikers become exhausted or trapped at such an elevated height, helicopters are the only means to rescue them.
However, there are no roads on the massive mountain, making it hard for helicopters to land. Not to mention, Mount Everest experiences frequent wind gusts of 150 to 200 MPH near its summit, increasing aircraft's difficulty to stabilize during rescue missions.
Two helicopters crashed on Tuesday while trying to land beneath the mountain's base camp. One person was killed and two others were injured in the crash, according to the New York Post, citing officials.
The wrecked aircraft was operated by different companies, Fishtail Air and Dynasty Air.
Helicopters Collide in Horrifying High-Altitude Crash
In a video obtained by NBC News, the propeller of one aircraft appears to fly off after they slam into each other.
The helicopters crashed at Pheriche village, which is at 4,200 meters (13,780 feet) altitude.
A 47-year-old tourist from India was killed in the crash, according to Bhupendra Thapa, a Solukhumbhu district administration officer. Local outlets reported that arrangements have been made to retrieve his body.
One of the pilots was also injured in the crash. The injured pilot and two passengers were transported to a nearby hospital.
Mount Everest is the tallest peak on Earth and takes professionals two to three weeks to climb.
Due to its tectonic placement, Mount Everest grows roughly 4 millimeters each year.
The demanding Mount Everest trek is especially popular in the fall season, after the rainy season has passed and before the harsh winter weather.
Mount Everest is located in Southern Asia on the international border of Nepal and Tibet.
The helicopter collision is the second incident near the Everest Base Camp this week. On Friday, Oct. 30, a fire broke out at a hotel in Dingboche, a popular stop for trekkers to recover while they acclimate to Everest's high altitude.
