I'm not entirely sure. A standard 727's max fuel is 9,806 gallons, with a range of 2,500 miles. So, figure 3,569 miles with 14,000 gallons. How far is Angola from NYC?

Figure it's about 6500 miles, give or take.

That means they would need a fuel capacity of 25,500 gallons to make the trip non-stop. That's an extra 15,000 gallons, or about 100,000 pounds of fuel. Figure the normal carrying capacity of a 727 is about 200 pax (40,000 pounds) plus cargo (20,000 pounds). Empty weight is 100,000 pounds and max takeoff is 209,500 pounds, so he would be overloaded by about 30%. The volume of the passenger compartment is certainly big enough to handle 15,000 gallons in tanks.

So, you figure if the pilot is willing to bust every safety rule and fit out the passenger compartment with tanks, he has just enought lifting capacity to allow a one-way to NYC.
