Climbing through a low line of clouds, rescuers aboard a military aircraft all Sunday tried to find a survey aircraft that crashed with the pilot and four passengers on board. It happened on Saturday in Alaska, high on a mountain ridge in the National Park and Denali Nature Reserve.

On satellite communication on the day of the crash, the pilot reported that there are wounded, but before the connection was interrupted, the authorities failed to get more information, writes The Daily Mail. The de Beavers de Havilland dropped about six o'clock in the evening and is believed to have crashed near the summit of Thunder Mountain, 3322 meters high, said Catherine Belcher.

So far, nothing has been reported about the condition of the pilot and passengers. Tourists, whose nationalities and names are not called, had to spend two nights on the mountain. By phone, Belcher said that over the alleged crash site, "low cloud cover," and said that the park's services are waiting for information from the HC-130 team, which is in the sky and is searching for.

Thunder Mountain is a mountain range with a knife structure that rises more than 900 meters above two glaciers, 22 kilometers southwest of the Denali peak, the highest peak in North America. It is reported that on board the aircraft have sleeping bags, stove, dishes, food and first-aid kit.

The HC-130 aircraft flew over the coordinates that came from the transmitter of the emergency locator of the crashed side and were named a pilot, said Lt. Col. Kandis Olmsted of the Alaska National Guard. The signal arrived at the Alaska Rescue Coordination Center at about 6:00 pm on Saturday.

"Researchers still can not see anything because of the cloud cover between them and the plane," Olmstead said on Sunday.

He also said that the HH-60 Pave Hawk helicopter with a rescue team, a National Park helicopter and another aircraft belonging to the private tourist company K2 Aviation, which owns the collapsed side, will participate in the search. K2 Aviation stated that it canceled the voyages at the moment and said that "the thoughts and feelings of the whole team with the families of our guests and the pilot involved in the incident".
