It’s directly related to flight safety. During spring, summer, and early autumn, a phenomenon called thermals occurs. At that time, the ground heats up from the sun, and warm air rises from it in the form of invisible “bubbles.” Although invisible to the naked eye, this can directly affect a balloon flight — in extreme cases, the pilot may lose control of the altitude. This phenomenon begins about three hours after sunrise and disappears around two hours before sunset. That’s why we can safely fly only during those times — early morning and late evening.
