Are planes polluting the sky and could airships be the solution?

As the aviation industry faces scrutiny for its carbon footprint, airships are being reconsidered as a sustainable alternative. Though once sidelined by airplanes, these lighter-than-air crafts offer potential for cargo transport and even drone delivery bases. While challenges like helium cost and buoyancy control remain, companies are developing innovative solutions to make airships a viable option for a greener future.
