The Concorde jet was a supersonic plane created in 1976 to speed transportation across the ocean. It traveled at twice the speed of sound, shortening a normal seven- to eight-hour transatlantic trip to three and a half hours. However, the Concorde still had to fly in the same atmospheric conditions as every other plane. Given this information, answer the following questions:
a. In which layer of the atmosphere did the Concorde cruise?
b. What are the characteristics of this layer that make it the ideal layer for the Concordeto travel?
c. Why wouldn't it travel higher?
d. Why wouldn't it travel lower?
