Supersonic commercial aircraft such as the Concorde and the Tupolev Tu-144 face many drawbacks and design challenges, including annoying sonic booms during flight, high development costs, safety issues, heavy weight, increased cost per seat compared to subsonic airlines, and insatiable fuel consumption. Sonic booms. A sonic boom is a sound created by a supersonic aircraft traveling through the air at a speed greater than the speed of sound. During flight, supersonic aircraft tend to generate a huge amount of sound energy, so disruptive that several countries are forced to limit or completely ban such aircraft from flying over the earth (Kachoria, 2013). However, countries such as the United States, Britain and France had only allowed transatlantic flights. High costs. The cost of developing a supersonic commercial aircraft (Concorde) was around £1.870 billion in the 1950s, funded by the French and British governments as reported by the Concordesst website and is 6 times the cost of developing a Boeing B747 (300 million of dollars) ) (Gates, 2010).
