It turned out to be a Sukhoi Superjet 100

… A large number of employees at the Siberia factory, responsible for working on the assembly of SSJ aircraft, were discovered to have falsified their university engineering degrees.

In 2012, a Superjet crashed into a mountain in Indonesia during a sales demonstration flight, carrying 37 aviation industry executives, members of the media, and eight crew members, killing everyone on board. Globally, the safety of the new aircraft was under scrutiny. The crash investigation revealed that the aircraft’s automatic collision avoidance system (designed to detect mountainous terrain) ‘was operational’, but had been ‘ignored by the pilot’, who was ‘possibly distracted by a conversation with a potential customer for the aircraft’. Consequently, pilot error was determined to be the primary cause of the crash.

In late 2016, 11 of Interjet’s SSJ100s were grounded due to a stabilizer (tail) defect. Russia’s Federal Air Transport Agency issued an airworthiness directive requiring “detailed inspection of the stabilizer joint straps and bracket attachment bands”. During this period, I spoke to a friend who was one of the world’s few SSJ pilots, flying for the Mexican airline. We met at the Farnborough Air Show in the UK, one of the industry’s largest trade events. What he told me was, frankly, eye-opening. For the sake of anonymity, I’ll refer to him as ‘George’. Over coffee, George revealed that he had decided to resign from Interjet, due to a lack of trust in the aircraft he piloted. He stated, “When we report genuine technical issues with this aircraft, Russia retaliates by telling Interjet that it is us [pilots] who are mishandling the aircraft”. George further described how he felt that the genuine concerns of the crew operating this new Russian jet were not being adequately addressed, leading him to leave the airline — he is now flying for Aeromexico.

bought a projector almost specifically for the eighth Game of Thrones season. The feeling from the first episode – it was like attending a reunion. And nothing much happened in it.

I just bought a Power Bank and stumbled upon products on Wish-e – 900000 mAh. Do these guys even realize how much a 900 amp-hour battery should weigh? About 60-80 kilograms including the box to fit it all in. Here, for example, is a two-volt 1000 Ah battery for sale: https://www.thesolarbiz.com/crown-batteries-2v-1000-ah-battery.html?fee=1&fep=199&gclid=Cj0KCQjw5J_mBRDVARIsAGqGLZA4I31w_uL5NKSHqCBpTLeUjg1lZPzg9RdxzfXGtVKhSOcGH98C7nIaAjAiEALw_wcB

Don’t fall for the scam. A fairly stable indicator of battery quality is its weight. “Off-brand” manufacturers try to reduce weight for higher capacity numbers. This is needed for marketing purposes, and it also lowers the cost of production, regardless of what’s inside. Normal manufacturers understand that the laws of physics can’t be circumvented, and they need to either reduce the capacity number or not fuss with the weight and offer a heavier battery. The greater the capacity, the more currents, and roughly speaking the wiring and electricity heavier it needs to be.

A 10000 mAh should weigh at least 210 grams. Accordingly, a 20000 mAh should weigh at least 420 grams.

There’s also the concept of Energy Density – https://www.epectec.com/batteries/chemistry/ which is energy per unit volume. This means that a 20000 mAh should be exactly twice as large as a 10000 mAh. It should consist of twice as many cells inside (looking like AA batteries).

Decided to read what they are writing in France about Notre-Dame after some time, opened what seemed to be the independent Le Parisien and was stunned: out of fourteen headlines on the main page, all fourteen contain “Macron”. And you talk about Channel One)

At the very least, in the middle there are cool presentations about Tesla’s image recognition system

Great interview @[711408:2048:Semyon Dukach] @[1512104653:2048:Elizaveta Osetinskaya]. A smart guy, interesting interview. Respect to both.

From my own experience, I see that impressions of other nationalities through life in the USA are shaped by people of those nationalities who have found the strength and opportunity to leave everything at home and come to the USA, and achieve something here. Not everyone is capable of this. Therefore, a hypothetical Korean in the USA differs from a hypothetical Korean living in Korea, and the attitude towards Koreans by “Americans in nth generation” is formed by observing those who “made it.” This creates a somewhat distorted impression of the nationality, as it is shifted, but still shifted towards the better. Hence, Russians here are not drunkards, but workaholics. And Koreans and Chinese – every other one is a mathematician, musician, and artist.

Liza told me that Americans are always amazed by her way of doing long division. It’s just that they, following the same principle, work everything leftwards and upwards – https://www.mathsisfun.com/long_division.html

For your Monday mood. Playing Melancholy Snowfall by Michele Mclaughlin. I’m late for the snowfall, but the flood of colors is at its peak here. In the middle of the video, there’s a little clip with cherry blossom.
