Terrifying video of Russian plane losing cabin pressure mid-flight shows how dangerous it's gotten to fly in Russia

• A Russian Boeing-737 had to make an emergency landing last week after cabin depressurization.
• A video of the incident shows panicked passengers with oxygen masks on their faces.

The video is short but terrifying.

Passengers on a flight from Sochi to Krasnoyarsk in Russia scramble to pull on their oxygen masks as the plane is forced to make an emergency landing. The lights are dimmed, a baby can be heard screaming, and a woman is seen holding her ears.

All of the 167 passengers and eight crew members on the Boeing-737 flight last week made it safely on the ground, state-owned news outlet RIA Novosti reported. The flight was operated by state-owned Rossiya Airlines, which is part of the Aeroflot group — Russia's largest airline.

But for many passengers, the experience was incredibly scary. One woman, identified only as Yulia, said she was writing a goodbye message to her husband as the plane rapidly descended, MailOnline reported.

"The plane seemed to be falling, and we flew down at incredible speed toward the ground. It was scary," she said, according to MailOnline. "I buckled up, and after that, I put on an oxygen mask. There was not enough oxygen. I was already starting to suffocate."

Musician Andrey Saltanov, who was also on the flight and verified the video to Insider, said: "The plane turned out to be ancient. The masks of the passengers next to me didn't even fall down ... Thank God we landed."

The main federal investigating authority in Russia told RIA Novosti that the flight was forced to land "due to depressurization of the aircraft cabin," adding that an investigation is ongoing.

Flying in Russia is becoming more dangerous

The emergency landing in Krasnoyarsk is just the latest of a string of alarming incidents happening on Russian flights.

In January alone, there have already been at least seven incidents with Russian airlines, according to a report by the independent Russian news outlet Arbat. One flight had to make an emergency landing due to a faulty toilet system, while another was forced to land due to an air conditioning malfunction, the outlet reported.

One expert told Insider that flying in Russia could become increasingly dangerous.

After Russia launched its attack on Ukraine last year, the country's aviation industry was hit by a slew of Western sanctions. In response, Russia illegally seized hundreds of leased aircrafts owned by international companies but operated by Russian airlines.

Because of the sanctions, Russia is not able to service these aircrafts or get spare parts delivered, leading to a decline in airline safety.

"Access to spare parts, which are sanctioned, is very limited," Denis Brailsford, the head of asset management at the UK's leading aviation consultancy group IBA, told Insider. "And the ability for Russian Airlines to perform repairs on those parts ... is very limited."

"Therefore, the ability for Russian airlines to maintain and repair their aircrafts will become more and more difficult over time. That could result in more of these events occurring," he added.

The lack of access even prompted the Kremlin to legalize "cannibalization" earlier this year, which means Russian engineers can now remove serviceable parts from one plane to keep others flying.

Russia has denied there are any problems with its aviation industry, with the head of Russia's aviation agency, Alexander Neradko, telling state media in January: "I am confident that it has not become more dangerous to fly."
