I’ve been fortunate to attend a couple of hot air balloon festivals. If you haven’t been to one or seen a hot air balloon set up for a flight, it’s quite a process, as these images demonstrate. Balloons are mobile and often carried in or on the back of a van or truck. The whole thing is unpacked. The burner used to heat the air needs to be attached to the basket. Then a large fan with a gasoline motor blows air into the envelope (the balloon itself). ONece there is enough air in the envelope, the burner is lit and begins to heat the air. The balloon slowly goes from lying on the ground to verticle. Finally, hop in and away you go. Oh yeah, this group had to notify a local airbase so that they did not cause any alarm or conflict with flight plans.
