In 1963, Boeing produced the three engine 727 to service smaller airports with shorter runways. The Boeing 727 allowed for low altitude, high-speed cruising capabilities with a cruising speed of 596 mph. This plane had a 189 capacity, and it carried passengers on both short connecting flights and long cross country ones. When Boeing first produced the aircraft, many company insiders were concerned about its profitability. However, this aircraft ended up having a very successful twenty-two-year production run with over 1,800 aircraft sold to over one hundred different airlines.
