Who was the first group to successfully fly around the world?

The first group to successfully fly around the world was eight US Army airmen, known as the "Around-the-World Flight" team. This landmark flight took place between 1924 and 1925, during which they completed their journey in a Douglas World Cruiser aircraft. Their expedition was a significant achievement in aviation history, showcasing the possibilities of long-distance flight and international cooperation.

The successful completion of this flight marked a pivotal moment in aviation, demonstrating the endurance, navigational skills, and teamwork of the crew members. The mission took them through various terrains and countries, illustrating the operational capabilities of military aircraft at the time. Their journey helped pave the way for future international flights and improved aerial navigation techniques.

In contrast, other choices listed, such as airlines or companies, were either not operational at the time or involved different types of aviation pursuits that did not include a round-the-world flight by a group of aviators.
