Hot-Air Balloons Are Useless

And yet, they have served Albuquerque pretty well:

The first hot-air balloons drew huge crowds, inspiring onlookers to cry, laugh, even faint. One witness wrote, “Since these exhibitions, there seems to prevail a kind of aerial phrenzy among us. The term ‘balloon’ is not only in the mouth of everyone, but all our world seems to be in the clouds.” For some, the new invention was the culmination of Enlightenment science, the pinnacle of human ingenuity. Grand schemes abounded: using balloons to carry mail, to improve cartography, to bombard enemy fortifications. Then, almost overnight, the fervor subsided as everyone sobered to the fact that these vehicles, which couldn’t be steered, were largely useless.
