The higher you climb the harder it gets: breathing supplementary oxygen becomes essential in lethal environments. That is why we need oxygen experts like EMS.
Sufficient oxygen supply is vital on the ground - and for survival at high altitudes above sea level. Without extra oxygen at these altitudes you would lose consciousness within seconds.
EMS aero found a tailormade solution for our mission.
We now have two independent ways to get sufficient oxygen into our blood. That is very important while climbing in the balloon - as well as in freefall.
