One of Project Loons hot air balloons just completed a journey round the world, but unlike Vernes Phileas Fogg who took 80 days to do so, Googles creation took but a mere 22 days. That far exceeds Mountain Views expectations (the team thought it would take around 33 days), all thanks to data collected by previous test flights. You see, the folks behind the project make sure to assess and use those findings to continue improving their balloons.
