What was one reason lighter-than-air craft were used in the arctic?

Lighter-than-air craft, such as hot air balloons and dirigibles, were employed in the Arctic primarily for exploration and searching for the North Pole during the late 19th and early 20th centuries. Their unique ability to float on air and operate at high altitudes made them particularly well-suited for the harsh conditions of Arctic exploration. These craft could navigate over icy landscapes and provide observational capabilities that were not feasible with ground-based expeditions or traditional ships, which could be hindered by pack ice or severe weather conditions.

The use of these craft was significant as it allowed explorers to gather information about previously uncharted areas, facilitating advancements in geographical knowledge and the pursuit of reaching the North Pole. Additionally, lighter-than-air craft could cover vast distances with relative ease compared to sledding across ice or making treacherous sea voyages, making them a logical choice for exploratory missions in the Arctic region.
