KC-707
With a full fuel load, Omega can carry approximately 160,000 pounds (25,000 gallons) depending on fuel type and temperature. At maximum landing weight, Omega can land with about 100,000 pounds (15,000 gallons) of fuel, so unless the flight is very short or has a low planned offload, Omega can usually take off with a full load of fuel. On a 10,000-foot sea level runway, Omega can take off with full fuel up to approximately 90 degrees Fahrenheit.
