Helium is totally inert, and is delivered separately to the site ready for inflation.The trailer itself folds out into a large platform, on which the balloon is inflated, operated and deflated.Two people can assemble the landing platform and inflate the balloon in a couple of hours, without any need for extra help.The tethered balloon Aero 2 is filled with 380m3 of helium, and can lift 280 Kg (620lbs). It is approved to carry two people to a height of 80 metres, (260Ft). Two passengers suspended in a harness and flying with nothing under their feet, rise smoothly to an incredible height. A unique system for advertising. The envelope can be totally covered with a specific decoration.
