====== Flight Data ======

The purpose of this page is to collect data on each flight so that a better balloon flight model may be built up.

E: This value was estimated from ascent and descent data below 60,000ft - due to GPS being disabled above this altitude.

Predicted values are using the burst3 model for Totex Balloons
