Heatproof AirframeConcorde's nose could heat to 260°F, a temperature that would shatter ordinary glass, so engineers devised a visor for the nose cone made of several layers of special glass to protect the flight deck.

Because the Concorde moves faster than sound, the air pressure and friction (collision with air molecules) really heat up the plane. The temperature of the aircraft's skin varies from 261 degrees Fahrenheit (127 degrees Celsius) at the nose to 196 F (91 C) at the tail.
flying on the Concorde was not a comfortable experience. this ultra fast supersonic jet. was once revered as the future of business travel, but its interior felt more like flying in a shoebox.
The reason commercial airplanes fly at 30,000 to 36,000 feet is because it places them in a unique part of Earth's atmosphere known as the lower stratosphere. The lower stratosphere is above the clouds, so commercial airplanes are protected against bad weather.
Planes have lower oxygen levelsIf this didn't happen, everyone inside the plane would die, as the low air pressure at the elevations planes fly (typically 35,000 feet or so) means there isn't enough oxygen present for your body to function.
The Concorde soared so high that you could see the Earth's curve. A ticket from London to New York on a flight operated by British Airways cost a whopping $7,574 (Rs5,50,000), which is equivalent to $12,460 (Rs9 lakh) today. But for the price, the Concorde experience wasn't exactly comfortable or luxurious.
Bathroom: The smallest room on Concorde was also a squeeze. Su Marshall, who flew on the airplane, said she was advised by a regular passenger to go before takeoff as the size made it impossible to pee once in the air.
The aircraft quickly proved itself unquestionably as it reached speeds of up to 1,354 mph. To put that into context, that is around 800 mph faster than a Boeing 747 and over 350 mph faster than the earth spins on its axis!
The power, or volume, of the shock wave depends on the quantity of air that is being accelerated, and thus the size and shape of the aircraft. As the aircraft increases speed the shock cone gets tighter around the craft and becomes weaker to the point that at very high speeds and altitudes no boom is heard.
Current rules prohibit commercial airplanes from flying at supersonic speeds over land because of the noise levels associated with sonic booms and the negative impacts to humans and animals.
According to John Britton the Concorde was the only aircraft that was ever certificated with reheat that boost the thrust up to accelerate it transonic to Mach 1.
Concorde used the most powerful pure jet engines flying commercially. The Aircraft's four engines took advantage of what is known as 'reheat' technology, adding fuel to the final stage of the engine, which produced the extra power required for take-off and the transition to supersonic flight.
Twenty Concorde aircraft were built, six for development and 14 for commercial service. All of these, except two of the production aircraft, are preserved. One aircraft was scrapped in 1994, and another was destroyed in the Air France Flight 4590 crash in 2000.
The Concorde was famously loud: a take-off at Washington airport in 1977 measured 119.4 decibels. By comparison, a clap of thunder hits 120 decibels while the pain threshold for the human ear is around 110.
At 40,000 feet its only 2.72 PSI. If outside air gets into the mask and is breathed, it contains one-fifth (20 percent) of the oxygen necessary for survival at 40,000 feet. The time of useful consciousness on ambient air only at 40,000 feet is 15 to 20 seconds.
