Best supersonic jets

Supersonic jets are said to be many times faster than ordinary passenger planes. Concorde was the first supersonic passenger jet, which started its service in 1976 and retired in 2003, after huge losses. The supersonic jets can travel at a speed of Mach 1.0 and over. Since it can carry only a few people, it is mostly used by rich businessmen and by presidents. Supersonic jets are also used in military purposes. But at present, no commercial supersonic jet is available in the world. There are efforts on to bring in some feasible supersonic jets for faster travel. Here are top 10 supersonic concepts around the world, which may become a reality some day.
