Hypersonic aircraft.

I have just read an article that China is attempting to build a hypersonic aircraft that could take you from say Bejing to New York in a matter of ours rather than the 13 hours it currently takes. There are so many problems with flying at very fast speed including sonic booms as the speed breaks the sound barrier, the heat of the friction on the body of the aircraft not to mention the cost per passenger. The only commercial aircraft that was in regular service was Concorde which was a joint Anglo-French project. It first went into service in 1969. They were all taken out of service following a crash in Paris just minutes after take off when debris from another aircraft pierced the fuel tanks on take off. Adaptations were initially made to the fuel tanks but its fate was sealed.They were finally taken out of service in 2003.There are 18 dotted around as museum pieces in the UK, France, Germany the USA and Barbados. I don't think Concorde ever made a profit and it was quite expensive to fly on. Even more than a First class fare. The fastest time London to New York was just under 3 hours at a speed of Mach 2.04 = 1,354 mph or 2,180 km/h. The noise of Concorde taking off was ear splitting. It only sat 100 passengers. The Chinese hypersonic planes are aiming for speeds of around Mach 5 and above. They will look similar to Concorde but with extra wings and extra hypersonic engines. Would you like to fly at hypersonic speeds?
