Definition: The term "aerialist" appears to be a misnomer or an oversight in English language, likely due to a confusion with various terms related to aerials, such as aviators, pilots, and aircraft mechanics. The Bible does not provide a specific term for this field of study, so we can't definitively determine the meaning of "aerialist." However, the concept of being an "airman" is widely accepted in the United States military, as it refers to someone who serves in the armed forces or has been trained and equipped to be employed in aeronautics. The term was often used for those who performed tasks related to aviation. The broader definition of aerialist might refer to someone who specializes in working with aircraft or flying bodies of water. This could include pilots, aviators, or navigators responsible for operating helicopters and other small aircraft on the ground. In this context, "aerialist" is likely a description of those involved in operations involving aircraft. In summary, the word "aerialist" has no direct Biblical usage; it is commonly used in modern English to describe someone who specializes in working with aircraft or flying bodies of water.
