The third edition of the GeoNord MEGA events, called Oxygen, took place from June 9 to 11, 2017. This event was held at the Saint-Omer airfield and at La Coupole d’Helfaut. The theme? Air!
Oxygen is an event packed with thrills, including a headlamp tour of the Eperlecques bunker and 20 Labcaches provided by Groundspeak, a first for a MEGA Event. Nearly 2,000 people of 20 different nationalities traveled to the North of France for this third edition.
