Since the inception of the jet, many of the models faced accidents while in operation. As much as 23 learjets crashed out which four had caused fatal disasters. By the year 2005, above half of the Lear 23 fleet faced accidents out of which 13 were fatal. The stats said that every single piece from the eight lear 23s went on to kill someone or the other. Recognizing the problem, a new model Lear jet 24 was created. Later models like the 25, 28 and 29 followed one by one. Lear jet has successfully evolved series of 30, 40 and 60. These are bigger, more efficient and also more secure compared to previous models. Some of the models were also preserved into the Museums of USA.
