Information on the case from local sources, may or may not be correct : A Polish tour group of four, including Sieniawski, Janusz Intek, Maria Libacka and Kazimierz Miernik, as well as their pilot, Craig Layson, flew out of Talkeetna, Alaska on August 4, 2018 to go on a one-hour sightseeing tour of Denali National Park. Their plane, a single-engine de Havilland DHC-2 Beaver airplane with the tail number N323KT, owned by K2 Aviation, never returned.
The plane was supposed fly over some glaciers and Denali Base Camp, then return to the airport at Talkeetna. The plane flew over the base camp at approximately 5:45 p.m. A short time later, its GPS satellite tracker suddenly stopped moving; it had crashed, and came to rest in ice and snow in a crevasse high on a knife-edge ridge of Thunder Mountain, at almost 11,000 feet latitude and about fourteen miles from the summit of Mount Denali.
Layson was able to make two calls by satellite phone in the hour after the crash, reporting he was trapped in the wreckAge at the time of disappearance: of the crashed plane and there were at least two fatalities, but both calls were quickly cut off. It's unclear how many people besides the pilot survived the initial crash. The plane was equipped with a first-aid kit, sleeping bags, a stove and a pot for boiling water.
Two days later, a search plane was able to locate the wreckAge at the time of disappearance: and lowered a National Park Service ranger onto the site for a few minutes. He located four bodies, but couldn't find the fifth. Four days later, another ranger was able to visit the site and found the fifth body in the back of the plane; no one had made it out of the wreckAge at the time of disappearance: .
Authorities were unable to recover anything at that time due to weather conditions, and by April 2019, park rangers discovered the plane was no longer in its original position. The wreckAge at the time of disappearance: , and the bodies of the five crash victims, have not been seen since.

A missing person is a person who has disappeared and whose status as alive or dead cannot be confirmed as their location and condition are not known. A person may go missing through a voluntary disappearance, or else due to an accident, crime, death in a location where they cannot be found (such as at sea), or many other reasons. In most parts of the world, a missing person will usually be found quickly. While criminal abductions are some of the most widely reported missing person cases, these account for only 2–5% of missing children in Europe.
By contrast, some missing person cases remain unresolved for many years. Laws related to these cases are often complex since, in many jurisdictions, relatives and third parties may not deal with a person's assets until their death is considered proven by law and a formal death certificate issued. The situation, uncertainties, and lack of closure or a funeral resulting when a person goes missing may be extremely painful with long-lasting effects on family and friends.
Several organizations seek to connect, share best practices, and disseminate information and imAge at the time of disappearance: s of missing children to improve the effectiveness of missing children investigations, including the International Commission on Missing Persons, the International Centre for Missing & Exploited Children (ICMEC), as well as national organizations, including the National Center for Missing & Exploited Children in the US, Missing People in the UK, Child Focus in Belgium, and The Smile of the Child in Greece.
