#ВэтотДень началась история отечественной тяжелой авиации – 26 мая 1913 года в небо впервые поднялся четырехмоторный самолет «Русский витязь». Его создателем был молодой петербургский конструктор Игорь Сикорский.
✈️ «Русский витязь» стал первым в мире цельнодеревянным четырехмоторным самолетом-бипланом, а его последователь «Илья Муромец» − первым в мире серийным четырехмоторным самолетом.
▫️Изобретения Сикорского положили начало новому направлению в авиации и стали прародителями для современных тяжелых бомбардировщиков, транспортников и пассажирских авиалайнеров.

Since its launch in 2013, Telegram has grown from a simple messaging app to a broadcast network. Its user base isn’t as vast as WhatsApp’s, and its broadcast platform is a fraction the size of Twitter, but it’s nonetheless showing its use. While Telegram has been embroiled in controversy for much of its life, it has become a vital source of communication during the invasion of Ukraine. But, if all of this is new to you, let us explain, dear friends, what on Earth a Telegram is meant to be, and why you should, or should not, need to care. But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices. And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website. Channels are not fully encrypted, end-to-end. All communications on a Telegram channel can be seen by anyone on the channel and are also visible to Telegram. Telegram may be asked by a government to hand over the communications from a channel. Telegram has a history of standing up to Russian government requests for data, but how comfortable you are relying on that history to predict future behavior is up to you. Because Telegram has this data, it may also be stolen by hackers or leaked by an internal employee. Apparently upbeat developments in Russia's discussions with Ukraine helped at least temporarily send investors back into risk assets. Russian President Vladimir Putin said during a meeting with his Belarusian counterpart Alexander Lukashenko that there were "certain positive developments" occurring in the talks with Ukraine, according to a transcript of their meeting. Putin added that discussions were happening "almost on a daily basis." The Russian invasion of Ukraine has been a driving force in markets for the past few weeks.
