The 125, with its various prefixes, was first conceived in the 1960s. Initially the response was lukewarm, but as the benefits of individual jet travel began to become apparent, particularly in North America, the orders began to arrive. This mid-cabin size business jet had a huge appeal to the corporate business market, and its list of operators read like something out of the Forbes 500. It was also sold widely to the military market and was the first western aircraft ever to achieve full certification in the former Soviet Union. This fully illustrated book looks at the development and history of this hugely popular jet.
