In this case it is not a matter of using all the runway, it is a matter of using all the runway and a bit more.
All the other planes turned and lined up on the runway just in front on the threshold lines, roughly putting the middle of the plane on the 10 painted on the runway.
But not the Insel Air plane. It came to the left so that the plane was sitting on the runway entirely prior to the threshold, covering the ---> ---> section of the runway. I am not a pilot in any way but that does not seem like a part of the runway you are expected to use for takeoff or landing.
The turbo prop plane took it one step further and came all the way out to the > > area on the extreme left of the runway. Got out of the plane, waved at everyone, got back in, revved up his engines and took off. I'm not sure what his passengers thought.
