A Facebook Live video purportedly showing the last terrifying moments inside the cabin on Yeti Airlines flight 691 before it crashed in Nepal on Sunday has circulated widely online, as search and recovery efforts continue on the ground.

The plane crashed while en route from the Nepalese capital Kathmandu to Pokhara, a tourist gateway to the Himalayas. There were 72 people on board, including four crew members, according to an airline spokesperson.

With all but one body recovered, the crash marks the country’s deadliest air disaster in more than 30 years.

The search to locate the last remaining victim is ongoing, Anil Shahi, a local official, said Tuesday.

The video was purportedly live streamed from inside the plane by a passenger, Sonu Jaiswal, with footage beginning moments before the plane crashed. It shows a plane window with the wing seen outside as the aircraft banks sharply to the left.

At one point, seemingly unaware of the impending danger, Jaiswal turns the video to himself, smiling slightly amid chatter and laughter in the background. Several passengers can be heard conversing excitedly in a mix of Hindi and Punjabi; one person says, “Look at that body of water, it’s excellent,” as the plane passes by a lake.

The mood inside the plane appears calm, with no emergency warnings from the pilot or airline crew. Seconds later, the video abruptly starts shaking with shouts heard; the camera loses focus, only showing flashes of light and loud noise, before the scene erupts in fire.

CNN has corroborated the video based on geolocation, a flight manifest and information on the Yeti Airlines website.

Jaiswal is listed as a passenger on the flight manifest, and the seat number listed for him on the airline website matches the visuals taken from inside the plane.

A close friend of Jaiswal in India, Arman Ansari, also confirmed it was Jaiswal seen in the video. He added that he was watching a Facebook Live stream from Jaiswal during the flight.

“We were watching it. We had watched for just a few seconds and then it got cut. We did not think much about it,” he said.

Aryaka Akhouri, the chief of Gazipur district in India where Jaiswal lived, said she had spoken to Jaiswal’s parents, and confirmed he was on the plane and the one filming the video.
