Airborne (S01E07)

The visionaries behind human flight exemplify determination and resilience. Lawrence Hargrave, once mocked for his innovative box kites, became a cornerstone of contemporary aviation. David Warren's development of the black box greatly enhanced flight safety, though he encountered significant opposition in bringing it to fruition. Jack Grant tirelessly worked for a decade to incorporate his life-saving slide-raft into aircraft. Meanwhile, it took an astounding 60,000 years for the creators of the returnable boomerang to finally gain acknowledgment for their contributions to aerodynamics.
