When World War II ended, the US military entered a golden age unprecedented in its history. This era marked a major turning point in the world of aircraft that could be called the "industrial revolution of the skies", or the era of the jet. The T-33 Shooting Star, which had been used as a conventional jet fighter, became obsolete in performance as jets, which were adopted in 1945, entered the mainstream and practical jet fighters began to achieve higher performance into the late 1950s. The Northrop T-38 Talon, which made its first flight in 1959, was highly acclaimed because, although it was a training jet, it was equipped with afterburners and was capable of supersonic speeds. It is now a legend that when Northrop developed the F-89 Scorpion air defense strike aircraft in the mid-1950s, it specially prepared the promotional red MA-1 jackets amid to get a contract of their aircrafts. Similarly for the T-38 Talon, Northrop produced the Indian-orange colored L-2 jackets in time for practical use, which shows the enthusiasm with which they promoted the T-38 Talon. Northrop even went to the trouble of providing jackets in time for the new fighter aircraft, which is a testament to the close and important relationship between fighter aircraft and flight jackets.
