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. 
• An expert told Insider that Western jets are deteriorating due to a lack of servicing and parts.

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.
