There was a series of five aircraft built for Braniff as the 707-200 series. Rather confusing: Boeing called these 707-220s, FAA said 707-200. Used JT4A-3, 15,800 lbs thrust (similar to J-75 military engines), for better t-o performance at high-altitude South American airports. One listing even shows these as being delivered as 707-220s, but as BA is Customer Code 27, others indicate 707-227.
