It takes years to develop a modern aircraft. But which one of the two giants – Boeing and Airbus – manages to do it faster?

Theoretically, it is not difficult to calculate the time it took to develop a particular model of aircraft. All we have to do is measure how many years, months or days were spent between the two points: when a particular airplane went into development and when its first production unit was delivered to the first customer.

The chart below shows how many years particular aircraft spent in the development cycle, including several significant checkpoints: the official launch of the program (often coupled with the first official order) and the first flight of the prototype. The most popular models are shown here, including significant modifications that often come with their respective generations.

Aircraft, developed by other companies, but sold by Boeing or Airbus (such as the Boeing 717 and the Airbus A220) are excluded, as are modifications of particular base model (such as the Boeing 737 MAX 9 or the Airbus A321 – derivatives of the 737 MAX 8 and the A320 respectively)....
