I have been trying to get evidence of a feature of the Boeing 777-300ER for many years. I previously posted on my efforts to get shots that showed the effect where the main gear bogie is locked to allow the aircraft to get a higher rotation angle at take-off. I have since had another go at this. Taking pictures during the winter has helped since the heat haze is a lot less obvious. Even so, the aircraft are usually quite a distance away. This time I managed to get a sequence that seems to show the effect quite well.
