- The balloon pilot was provided a detailed weather briefing prior to the flight which called for light and variable winds. Soon after departure, the winds increased from 4-6 knots to 6-8 knots, gusting to 15 knots. The pilot flew around waiting for winds to subside to no avail. The pilot was forced to land with the prevailing high winds when he started getting low on fuel.
