Takeoff on rwy 17 from Porto to Zurich. The flight was slightly late (around 20 minutes due to traffic) and the pilots announced they would attempt to catch up some time by flying at maximum speed. Although this is not visible from the video, this might be the reason why the accelleration during takeoff was really strong on this still quite long runway of approx. 11500 feet. The pilot obviously did not use reduced takeoff thrust. After the takeoff the plane turned towards east which allowed me to film the airport area.
