Прототип частного сверхзвукового самолета Boom Supersonic XB-1 преодолел звуковой барьер, разогнавшись до 1.1 Маха (свыше 1350 км/ч) ✈️

Разрабатывается он с 2014-го, а в будущем на его основе хотят создать сверхзвуковой пассажирский лайнер, который станет третьим в истории после советского Ту-144 и британо-французского Concorde.

По плану он сможет разгоняться до 1.7 Маха (2080 км/ч), а перелет из Лондона в Нью-Йорк займет ~3.5 часа против 7-8 на обычном самолете.

Telegram | DID YOU KNOW?

Date: |

False news often spreads via public groups, or chats, with potentially fatal effects. Two days after Russia invaded Ukraine, an account on the Telegram messaging platform posing as President Volodymyr Zelenskiy urged his armed forces to surrender. Investors took profits on Friday while they could ahead of the weekend, explained Tom Essaye, founder of Sevens Report Research. Saturday and Sunday could easily bring unfortunate news on the war front—and traders would rather be able to sell any recent winnings at Friday’s earlier prices than wait for a potentially lower price at Monday’s open. Right now the digital security needs of Russians and Ukrainians are very different, and they lead to very different caveats about how to mitigate the risks associated with using Telegram. For Ukrainians in Ukraine, whose physical safety is at risk because they are in a war zone, digital security is probably not their highest priority. They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders. Recently, Durav wrote on his Telegram channel that users' right to privacy, in light of the war in Ukraine, is "sacred, now more than ever."
