The Tu-144 was the world's first commercial supersonic transport aircraft with its prototype's maiden flight from Zhukovsky Airport on 31 December 1968, two months before the British-French Concorde. The Tu-144 was a product of the Tupolev Design Bureau, an OKB headed by aeronautics pioneer Aleksey Tupolev, and 16 aircraft were manufactured by the Voronezh Aircraft Production Association in Voronezh. The Tu-144 conducted 102 commercial flights, of which only 55 carried passengers, at an average service altitude of 16,000 metres (52,000 ft) and cruised at a speed of around 2,200 kilometres per hour (1,400 mph) (Mach 2). The Tu-144 first went supersonic on 5 June 1969, four months before Concorde, and on 26 May 1970 became the world's first commercial transport to exceed Mach 2.
The Tu-144 suffered from reliability and developmental issues, and with the 1973 Paris Air Show Tu-144 crash, restricted the viability for regular use. The Tu-144 was introduced into passenger service with Aeroflot between Moscow and Almaty on 26 December 1975, but withdrawn less than three years later after a second Tu-144 crashed and retired on 1 June 1978. The Tu-144 remained in commercial service as a cargo aircraft until cancellation of the Tu-144 program in 1983. The Tu-144 was later used by the Soviet space program to train pilots of the Buran spacecraft. The Tu-144 made its final flight on 26 June 1999 and surviving aircraft were put on display across the world or into storage.
Soviet son: Mom can I have Concorde at home?
Soviet mom: We have Concorde at home.
Concorde at home: I am a Tu-144 bruh.

(also referred to as the QM2) is a British transatlantic ocean liner. She has served as the flagship of Cunard Line since succeeding Queen Elizabeth 2 in 2004.
The ship was officially named Queen Mary 2 by Queen Elizabeth II in 2004 after the first RMS Queen Mary of 1936. Queen Mary had in turn been named after Mary of Teck, consort of King George V. With the retirement of Queen Elizabeth 2 in 2008, QM2 is the only transatlantic ocean liner in regular service between Southampton, England, and New York City, United States. The ship is also used for cruising, including an annual world cruise.
She was designed by a team of British naval architects led by Stephen Payne and was constructed in France by Chantiers de l'Atlantique. In 2004, QM2 was the longest, at 1,131.99 ft (345.03 m), and largest, with a gross tonnage of 148,528 GT, passenger ship ever built. She remains the largest ocean liner ever built.
QM2 was intended for regularly scheduled crossings of the Atlantic Ocean. The cost was increased by the high quality of materials; having been designed as an ocean liner, 40% more steel was used than for a cruise ship. She has a maximum speed of just over 30 knots (56 km/h; 35 mph) and a cruising speed of 26 knots (48 km/h; 30 mph), which is faster than a cruise ship. QM2 uses integrated electric propulsion to achieve her top speed. Diesel engines, augmented by gas turbines, are used to generate electricity for motors for propulsion and for onboard use.

The Boeing 2707 was an American supersonic transport (SST) project. After winning a competition for a government-funded contract to build an American SST, Boeing began development at its facilities in Seattle, Washington. The design emerged as a large aircraft with seating for 250 to 300 passengers and cruise speeds of approximately Mach 3. It was intended to be much larger and faster than preceding SST designs such as Concorde and Tu-144.
The SST was the topic of considerable concern within and outside the aviation industry. From the start, the airline industry had noted that the economics of the design were questionable, concerns that were only partially addressed during development. Outside the field, the entire SST concept was the subject of considerable negative press, centered on the issue of sonic booms and effects on the ozone layer.
A key design feature of the 2707 was its use of a swing wing configuration. During development the required weight and size of this mechanism continued to grow, forcing the team to start over using a conventional delta wing. Rising costs and the lack of a clear market led to its cancellation in 1971 before two prototypes had been completed.
FAA: President Kennedy, we have fallen behind the British, French and the Soviets in Supersonic aircraft development.
John F Kennedy: Damn it, start the B2707 program. Boeing will go the job.
Boeing: We've ran out of tecnology
This is a imaginal country which turns China and the Soviet Union into one communist entity. The name stands for United Communist Russian Chinese Republic. It is combining the PLA and the Red Army. If not the Sino Soviet Spilit happened, this nation might be a reality. USA should be scared by this UCRCR
Friedrich Engels: What if two future communist nations merge together like the currant Qing and Russian Empire into two communist nations, then they merge into one??
Karl Marx: That would be UCRCR!!

Chronology
Predecessor Tesla Roadster (first generation)
The Tesla Roadster is an upcoming all-electric battery-powered four-seater all-wheel-drive sports car concept in development by Tesla. Inc. Tesla has claimed that it will be capable of 0 to 60 mph (0 to 97 km/h) in 1.9 seconds, which would be quicker than any street-legal production car as of the announcement in 2017. The Roadster is the successor to Tesla's first production car, which was the 2008 Roadster.
Tesla CEO Elon Musk has said that Roadster should ship in 2023. Musk said in a tweet that higher-performance trim levels will be available beyond the base specifications, including a SpaceX package which would "include ~10 small rocket thrusters arranged seamlessly around the car" which would supposedly allow for dramatic improvements in "acceleration, top speed, braking & cornering".
Elon Musk: Hey can we remake our first hypercar but add a rocket booster?
Franz von Holzhausen: Yes, we can call that Tesla Model R
Elon Musk: Nah, I will call it Tesla Roadster 2.0
