Toulouse

Toulouse is the manufacturing base of Airbus in France. When driving outof the Balgnac airport in Toulouse, the sign of Airbus is very often jumped in front of you. My brother-in-law currently works in Airbus. From him I knew for the first time that the gas tank of an aircraft are located on the wings and the flow of the liquid oil in the wings helps stabilizing the aircraft and there is complex computation model on the statas of an aircraft with respect to the position of the oil in the wings--I guess that should be one important reason why the cheapest seats are always over the wings.

As an industrial city, Toulouse is not small, although the center is not very large either, compare to China cities, of course.
