Predictions

New Project
Balloon pressure release valve
Goal: achieve higher altitudes with our payloads
Means: cut down part of train at 50,000-70,000ft
Lighter payload will allow the balloon to ascend quicker
Pressure-release valve should allow balloon to reach higher altitudes before bursting
Secondary Goal: Break some altitude records

145,590.60 ft - current record on arhab.org
World record is 173,900 ft, Japan 2002
