I dive into my old collection of Popular Mechanics magazines and get inspired to build something! I found Ernest Winter's air screw bike, so I tried to build it. He claims it can hit 20 mph, can I match his speed? How will I build the propeller? How can I power it with my feet? Will it be fast enough to fly? How does that compare to a huge fan? I continue the journey to check it out and more! Stabila Protractor New Welding Hex Lock Kit Professional cyclists helped us on our journey More fun stuff

y the mid-1950’s, the United States had developed a state-of-the-art, all jet-powered bomber force. The newly introduced Boeing B-52 Stratofortesss could reach the Soviet Union from just about anywhere in the world. The soon-to-be-introduced supersonic Convair B-58 Hustler could dash to supersonic speeds. Both aircraft were engineering marvels. But even so, they were expected to perform poorly over Soviet airspace. The B-52 flew too slowly to stand a chance against the latest generation of Soviet interceptors, while the supersonic B-58 lacked the required range and payload to be truly effective. The U.S. Air Force needed a next generation bomber that would combine the capabilities of both these aircraft. A plane that could fly at supersonic speeds, travel long distances and carry large payloads. To meet their new bomber requirements, the Air Force contracted leading aerospace companies to explore radical new technologies, like nuclear powered jet engines for extending aircraft range and high energy ‘zip-fuels’ to increase aircraft performance. Boeing and North American Aviation would play a vital role in research. But given the limitations of technology, the most practical solution put forward was the ‘dash concept’ which detailed an enormous aircraft that would travel subsonically most of the way to its target, before jettisoning outer portions of its wings and fuel tanks to make a supersonic dash. These concepts were studied in an era of extraordinary advances in aviation technology and engineering, and by 1957 it became apparent that it might be possible to build a large, long range bomber that could fly supersonically over its entire mission. In 1957, the Air Force outlined their specifications for an aircraft that would cruise at Mach 3, up to an altitude of 75,000 feet. It was expected to offer a similar payload and range to the B-52. Boeing and North American Aviation both submitted design concepts, but North American’s proposal was selected for development. A key principle in North American’s design was compression lift, which would significantly improve the aircraft’s lift to drag ratio when flying at high supersonic speeds. The new bomber would be designed as the B-70 (XB-70 in experimental prototype form) and named the Valkyrie. Given the XB-70’s incredible speed and altitude capabilities, it was expected to be practically immune from interception. But developing such an ambitious bomber would be fraught with technical challenges. More critically, huge advances in missile technology would soon threaten to render the entire concept of a supersonic intercontinental bomber obsolete.

Chinese President Xi Jinping met with Russian leader Vladimir Putin in Beijing hours before the Winter Olympics opening ceremony on February 4, 2022. This was Xi’s first in-person meeting with Putin in nearly 2 years.

The United States has deployed several thousand troops to eastern Europe to boost Nato forces amid the threat of a Russian invasion of Ukraine, said Pentagon spokesman John Kirby on February 2, 2022. According to the official, the US military will bolster forces in Nato countries but will not enter Ukraine. About 2,000 US-based troops will be sent to Poland and Germany, while 1,000 soldiers currently based in Germany will be moved to Romania to strengthen Nato’s eastern flank.

CY Leung was Hong Kong chief executive for a single term that ended in 2017. Now, as an elder statesman trusted by Beijing, he has become an active, vocal and influential figure in the city’s affairs. And he has kept everyone guessing as to whether he wants to take another shot at Hong Kong’s top job in a changed political environment after the anti-government protests of 2019. In this episode of Talking Post, Leung tells SCMP chief news editor Yonden Lhatoo about his views on leadership, Hong Kong’s future and a range of issues including pandemic control, national security and press freedom.

As Russia continues to build up forces along its border with Ukraine, the Kremlin has also been sending military equipment to neighbouring Belarus for a joint exercise dubbed Allied Resolve 2022, adding to fears of an imminent invasion. Some experts warn that Russia could send troops to attack Ukraine through Moscow-friendly Belarus. Russia also plans to hold similar exercises near the borders of Nato members, Poland and Lithuania. Ukrainian forces, meanwhile, continue to man defensive positions within the country. Some soldiers have voiced concerns that Russia is not serious about achieving a resolution in its diplomatic talks with Washington.

Russia’s move to amass some 100,000 troops at its border with neighbouring Ukraine has raised tension between Moscow and Western government to a boiling point. US President Joe Biden said in a press conference January 19, 2022, that he expects Russia to make a move on Ukraine, warning that it would be met with a severe and coordinated economic response. Meanwhile, Russia has moved troops to Belarus for joint military exercises planned for February, and has strengthened its military presence near Ukraine. On January 20, US Secretary of State Antony Blinken met British, French and German officials to discuss Ukraine. Britain has delivered anti-tank systems to the country and Canada has reportedly deployed special forces there. In 2014, Russia annexed the Crimean peninsula, which is internationally recognised as part of Ukraine. Moscow has denied planning to attack its western neighbour. The deployments of Russian troops, it said, only serves as a warning to keep Ukraine out of Nato.

The Chinese capital’s first locally transmitted case of the new strain of the virus that causes Covid-19 was reported on January 15, 2022, as a throng of local transmission chains was being found throughout the country with only weeks to go before the Lunar New Year holiday and the start of the Beijing Winter Olympics.

China’s new homegrown fighter jet, the J-20, is being put through its paces. New training sessions have been organised by the People's Liberation Army Air Force, aimed at improving the combat use of the aircraft. Drills have been conducted to help pilots master the cutting-edge, fifth-generation stealth fighter. Related story: Close calls for China’s J-20 before stealth fighter’s deployment, Avic says

The Beijing 2022 Olympic Committee announced on January 17, 2022, that tickets to watch the Winter Games will not be sold to the public. The decision comes less than three weeks before the Games’ opening as China battles Covid-19 outbreaks. Sporadic outbreaks have spread to cities including Xian, Shenzhen and Tianjin, which is near to Beijing. On January 15, Beijing reported its first case of the Omicron coronavirus variant.

The Pacific island nation of Tonga is still largely cut off from the outside world days after a massive undersea volcanic eruption on January 15, 2022, triggered a tsunami and blanketed islands in thick layers of ash. Several deaths have been reported, but there are fears that the number of casualties could climb as information emerges about the scale of the devastation. Rescue and relief efforts have been delayed because of severed communication links, heavy ashfall at the country’s main airport and concerns that aid deliveries could spread the coronavirus. Tonga is reportedly nearly Covid-free, with only a single confirmed case, according to the World Health Organization.

Japan and the US have further deepened security ties amid growing tensions in the region. The two countries agreed to increase cooperation on scientific research related to military technologies. Tokyo and Washington cited China’s growing military presence in the region as a cause for concern, as well as ongoing missile tests by North Korea. It follows a “historic” deal signed between Japan and Australia, Japan’s first military agreement with another country since the US defence pact in 1960.

The Taiwan military held urban and aerial-combat drills on January 6, 2022, as incursions and sabre-rattling by mainland China continued. Beijing says the self-ruled island will one day be put under its rule, by force if necessary. In 2021, Beijing sent a record 970 military aircraft into Taiwan’s air defence zone, double previous years. The ongoing threats have prompted a series of new military drills on the island, to prepare for a possible invasion.

America is a long-standing ally of Taiwan's rulers and is legally bound to provide the island with weapons to defend itself due to treaties passed in the 1970s.
