Great job and this take off is way different from sea level such as JFK Airport its due to the fact that Mexico City Benito Juarez airport is at a much higher elevation therefore having hot and high conditions like Denver Stapleton Airport one mile above sea level
hash2all The long take roll has nothing to do with the jet being heavy!! It has to do with the fact that mexico city is a high altitude airport, the engine performance is not as good because this is not sea level
