Le Mondial Air BallonsMondial Air Ballons, formerly known as Lorraine Mondial Air Ballons, is the largest gathering of hot-air balloons in the world. Mondial Air Ballons holds the record of 433 hot-air balloons lined up simultaneously.

Created in 1989 by Philippe Buron Pilâtre, the Mondial Air Ballons is an event that brings together more than 400,000 spectators over ten days at Chambley airfield. On this occasion, the Specilor, Mazet Mercier and Jung subsidiaries, on behalf of Primagaz, took part in supplying the hot-air balloons with LPG, so that the cylinders could be recharged after each flight.
