| - | In practice the difference between Helium and Hydrogen is much less in terms of altitude attained. For example a 1Kg payload on a HY-1000 balloon at 5m/sec ascent rate would typically achieve around 32.0Km (105,000ft) on 97%Helium and 33.1Km (108,000ft) on Hydrogen – so **only 3% better.** | + | In practice the difference between Helium and Hydrogen is much less in terms of altitude attained.
