Stopping at Chalon. The nerves needed to be calmed with coffee and a comfort break. The 12 euro landing fee was partially softened by the weather reports which seemed reasonable. In addition, the airport staff contacted Sezanne, to confirm we were en route for unleaded fuel, therefore we opted not to re-fuel.
Another 2 hour flight found us at Sezanne, which is fast becoming an important waypoint for UL91. All the aircraft were thirsty after 4 hours flying. Another coffee and comfort break and on to the third leg.
