Russian plane crash kills all 71 people on board : Accident footage.
According to Daily mail , Nadezhda Krasova, five, the youngest victim in the crash, died along with her mother Oksana Krasova, 32, after the Antonov An-148 airliner broke up in mid-air, according to eyewitness reports. The Saratov Airlines regional jet disappeared from radar screens a few minutes after departing from the capital’s Domodedovo Airport.
The An-148 was developed by Ukraine’s Antonov company in the early 2000s and manufactured in both Ukraine and Russia.
Russian state news agency Tass said the plane that crashed had been flying since 2010, with a two-year break because of a shortage of parts. The plane was ordered by Rossiya Airlines, a subsidiary of Aeroflot, but was put into storage between 2015 and 2017 because of the parts shortage.
Tass reported that it re-entered service for Saratov Airlines in February 2017. Initial Russian reports blamed weather or human error, but it was unclear how these squared with claims that the plane broke up in the sky.
Russian media reported that the emergency services were unable to reach the crash site by road and that rescue workers walked to the scene on foot. Emergency services said in a statement that more than 150 rescue workers were deployed to the site.
Aviation website FlightRadar reported the aircraft was last measured falling at a rate of 22,000ft per minute.
Fragments from the Antonov An-148 airliner were found in the Ramenskoye area, about 40 kilometers (25 miles) from the airport. Footage on state television showed them strewn across a snowy field with no buildings nearby.
Transport Minister Maxim Sokolov said Sunday afternoon that ‘judging by everything, no one has survived this crash.’ Russia’s Investigative Committee said all possible causes were being explored.
The plane crashed, with 65 passengers and six crew aboard, just a few minutes after setting off Orsk, a city in the Urals, around 1,000 miles southeast of Moscow. Like many of the victims, Nadezhda and her mother were from Orsk, in Orenburg region, which will mark a day of mourning on Monday.
Also among the dead were Evgeny Livanov, 12, and Ilya Poletayev, 17, according to local reports. Stewardesses Anastasia Slavinskaya, 29, and Viktoria Koval, 21, and second pilot Sergey Gambaryan, 34, also died.

Can Airline Seat Cushions Be Used As Life Jackets?
In the event of an aircraft ditching into water, there’s a common question: Can aircraft seats serve as an alternative to life jackets for flotation? The answer lies in understanding their respective functions.
While seat cushions can provide some buoyancy in water, they are not intended nor certified to function as life jackets. Their primary purpose is to offer cushioning for passengers during flight. On the other hand, life jackets are meticulously engineered to keep individuals afloat in water, equipped with buoyancy materials, secure straps, and reflective elements for visibility. They offer numerous advantages over mere cushions.
While a seat cushion might offer temporary assistance in staying afloat, it’s not a dependable substitute for a proper life jacket during an emergency. It’s crucial to utilize approved safety equipment when near bodies of water. A life jacket, designed to keep a person buoyant for extended periods, offers the rigidity needed for prolonged flotation and allows for easy movement of the arms to navigate effectively.
What fabric is used in aircraft seats?
Seats are meticulously designed to fulfill multiple purposes, ensuring passenger comfort, safety, and protection from unforeseen circumstances like fires and accidents. A typical design incorporates an aluminum frame with blocks of polyurethane foam affixed to it. Additionally, a layer of fire-resistant fabric, such as Kevlar or Nomex, is often applied over this framework, topped with a layer of cloth or leather.
Leather seats, while luxurious, are more expensive compared to traditional cloth seats. The majority of fabrics used in seat upholstery contain at least 90% wool fiber, with the remainder typically consisting of polyamide (nylon). Wool stands out as the primary fiber chosen for commercial airline seating fabric due to its desirable properties and suitability for such applications.
What is the lightest economy seat?
In recent times, airlines have been downsizing seat dimensions to accommodate more passengers, resulting in reduced cushion length and leg space. This contrasts with earlier times when airlines offered more generously cushioned seats and ample amenities.
According to Recaro Seats Company, their SL3710 model represents the lightest economy class seat available, weighing in at a mere 8 kg (17.6 lb.), setting a new standard in aircraft seating.
For individuals weighing more than 350 pounds, fitting into a standard economy-class seat can be a challenge due to the narrower dimensions. Economy seats, also referred to as “coach,” “standard,” or “main cabin” seats, typically range from about 40 to 48 centimeters in width, further emphasizing the need for more accommodating seating options.
