What is aircraft range

When talking about aircraft range and it's said to be 1000 miles, is that 500 miles each way or 1000 miles each way?

Well, wikipedia defines Range (aircraft) as "The maximal total range is the distance an aircraft can fly between takeoff and landing, as limited by fuel capacity in powered aircraft, or cross-country speed and environmental conditions in unpowered aircraft." Seeing as it says "between takeoff and landing" I do believe that means it'd be 500 each way, because if it was 1000, then it would just run out of fuel and crash. Basically "between takeoff and landing..." is the entire time it's in the air, going up, out, back, and down.
