This one was taken at the extension of the runway, possibly 200-300 m after actual take off.
Then this one was taken approximately at the same spot, may be another 200 m off from the runway course. I like the light and the shadow wrapping over the fuselage and the sharpness of the details.
And the last one for you - taken from the opposite end of the runway, uncropped. It was getting dark, but the 2.8 opening allowed for keeping going. Interestingly, the lens requiring tripod or monopod while shooting at close range, produces consistently sharp images of moving objects at infinity. Highly recommended.
