History In 1966, the Lear 24 was introduced at a higher weight and with upgraded GE CJ610-6 engines that produce 2,950 pounds of thrust. Three rectangular windows replaced the single oval window on each side of the cabin. Other improvements included a bird-proof windscreen and increased cabin pressure differential for higher altitude operation.
