Halflings, the eagle jockeys
Halflings were the first humanoids to fly without magic. Once kites were discovered, the lightest of the short folk immediately began figuring out how to soar with them.
Many groups have a distinct style of paragliders inspired by ornate kites, thanks to this history.
Before even the birth of kites, halflings were pursuing flight by another means -- golden eagles. They were first employed by the military for aerial assault and carrying parachuters.
Now eagles are popularly employed in recreational skydiving and back rides. As they've grown bigger and semi-domesticated, these birds have become accessible to short folk of all types.

The innovation of flight never stopped! In the modern day, halflings are known for myriad flying creatures who can carry them -- giant bats and magically enhanced insects the most notable among them. Though balloon cities are most closely associated with gnomes, halflings have made their own contributions. They helped create massive hot air cities and mastered farming at high altitudes, as they did on the ground.
And we can't forget perhaps the greatest aerial achievement of the short folk. Space travel was a combined victory of all peoples, and we all cheered when a half dozen halflings took to black skies and stepped into the First Dwarven Star Station.
Who knows what they'll achieve next? It seems, for halflings, even the sky is no limit!
