The following is a concise summary of the transcript:
The transcript tells the story of the Concorde, the world's first supersonic passenger aircraft, developed by France and the United Kingdom in the 1960s and 1970s. It describes the technical challenges, innovations, and achievements of the Concorde project, as well as its commercial failures and eventual demise in 2003. It also mentions the rival projects of the United States and the Soviet Union, and how they failed to compete with the Concorde. It ends with a note on the current efforts to revive supersonic flights and a call for more science in Brazil.
1. On January 21, 1976, two Concordes, one from British Airways and the other from Air France, simultaneously carried out their first commercial supersonic flights.
2. The Air France Concorde took a route from Paris to Rio de Janeiro, with a stop in Senegal for fuel.
3. Concorde's commercial flights began on January 21, 1976, and ended on October 24, 2003.
4. The Concorde was operated by British Airlines and Air France.
5. The Concorde offered extremely fast luxury travel, with a cruising speed of 2,158 kilometers per hour.
6. The fastest commercial plane currently is the Boeing 747 8, which has a cruising speed of 917 kilometers per hour.
7. The route from Rio to Paris, which takes an average of 12 hours, was done in just over six hours with Concorde, including the stop in Senegal.
8. The speed of the Concorde was faster than the speed of the earth's rotation.
9. Even before commercial flights began, the Concorde raced against a Boeing 747 to demonstrate the speed of supersonic travel.
10. The Concorde departed from Boston to Paris at the same time as the Boeing 747 departed from Paris to Boston.
11. In 1947, the American air force pilot Chuck Yeager broke the sound barrier aboard the experimental plane Bell X-1.
12. In the 1950s and 1960s, the governments and aviation companies of the United States, France, United Kingdom, and Soviet Union began a technological race for the development of a supersonic passenger aircraft.
13. In 1962, due to the enormous costs, the United Kingdom and France signed an agreement to develop the world's first supersonic passenger airline together.
14. The French Aérospatiale, the predecessor of Airbus, and the British British Kraft Corporation were responsible for the structure of the aircraft.
15. The French SNECMA and the British Rolls Royce developed the jet engines with the aircraft using four of them.
16. In 1967, the American president John Kennedy launched a competition to build a rival to the European model.
17. The Soviet Union's Tupolev Tu-144 became the world's first supersonic commercial airliner to fly.
18. The Soviet Tupolev did not get very far, suffering a series of accidents due to failures in the project.
19. The Concorde project, despite the great engineering challenges, was successful.
20. The Concorde's design was not made by computers but by mathematical calculations and trial and error through wind tunnels.
21. The Concorde's wings were triangular, providing stability that could withstand stresses at enormous speeds.
22. The Concorde did not have horizontal compensators as it would cause enormous drag.
23. The Concorde flew at enormous altitudes, reaching 18 thousand meters, where there was little turbulence due to the rarefied air.
24. The Concorde had four turbo engines I'm already clean 593.
25. The Concorde carried out its last commercial flight on October 24, 2003, ending an era in the history of aviation.
