Response to: Where are you going? Where have you been? Where are you going? Where have you been? Is an all in all interesting piece.

ascent – and safe descent – in modern times took place by hot-air balloon in the 18th century. Each of the two World Wars led to great technical advances. Consequently the history of aircraft can be divided into five eras: Aerostats use buoyancy to float in the air in much the same way that ships float on the water. They are characterized by one or more large gasbags or canopies‚ filled with a relatively low-density gas such as helium‚ hydrogen‚ or hot air‚ which is less dense than the surrounding
