Winds are generated by the sun, which heats different parts of our planet differently. The equator gets more heat, the poles less, and the cool air rushes to replace warm air, which rises. This is the cause of wind. But within the balloon basket, there is no sensation of wind, because a balloon follows air currents. And when the propane burner is off, a silence is invoked.
Ballooning is less old than our nation.
Like radiation and existentialism, balloons were invented by the French. The science of hot air balloons is the same principle which allows open coolers in supermarkets. The milk does not, because heat rises and coldness sinks. The cold air encircles the cartons, maintaining their chill. Meanwhile, warm air drifts up over one's head, to dwell on the supermarket ceiling.
