The search for a sightseeing plane with five people on board was to resume Monday morning, more than a day after it crashed in Denali National Park in Alaska, CBS Anchorage affiliate KTVA-TV reports. Rescuers aboard a military aircraft failed to find the aircraft Sunday. It was carrying the pilot and four passengers when it went down high on a mountain ridge Saturday night.

The pilot reported on his satellite phone Saturday that everyone had survived but there were injuries, KTVA-TV says. But authorities couldn't get details before the satellite connection dropped. Some 20 hours after the de Havilland Beaver plane went down around 6 p.m., the plane is believed to have crashed near the summit of 10,900-foot-high Thunder Mountain, park spokeswoman Katherine Belcher said.

There was still no word on the conditions of the pilot and passengers.

The tourists, whose identities and nationalities have not been released, and pilot had to spend the night on the mountain.

"There's definitely low cloud cover," Belcher said in a telephone interview. "We're waiting for an update from the HC-130 crew that's up in the air."

Thunder Mountain is a knife-edge ridge rising about 3,000 feet above two glaciers, 14 miles southwest of the summit of Denali, North America's highest peak. The plane was reportedly carrying sleeping bags, a stove, a pot, food and first-aid kit, Belcher said in a statement.

An Air Guard HC-130 was flying over coordinates that came from the plane's emergency locator transmitter and were offered by the pilot, said Lt. Col. Candis Olmstead of the Alaska National Guard. The plane's ELT beacon alerted the Alaska Rescue Coordination Center around 6 p.m. Saturday.

"Searchers don't have eyes on aircraft yet because of cloud cover between them and the aircraft," Olmstead said Sunday.

An Air Guard HH-60 Pave Hawk helicopter with a rescue crew, a National Park Service helicopter and another plane owned by the private tour company, K2 Aviation, that operates the downed plane can help with the search, Olmstead said.

K2 Aviation said it has canceled flight tours for now.

"The entire K2 family sends their thoughts and prayers to the families of our guests and the pilot involved in the incident," the company said in a statement. "Search efforts continue and K2 Aviation is cooperating fully with the Alaska State Troopers, the National Park Service, Alaska Air National Guard, the National Transportation Safety Board, the Federal Aviation Administration and other authorities involved."

The company, based in Talkeetna, Alaska, offers glacier landings.

"The glaciers found in Denali National Park are like no others in the world. Beneath the towering mountain peaks, you'll understand why these immense ice fields attract people from all over the globe," K2 Aviation says on its website.
