The Mystery of the Small Aircraft Deliveries
Explanation:
The question refers to a historical event, where it describes an operation involving small aircraft delivering packages to various U.S. cities. However, the question seems to be a fill-in-the-blank format without a specific context given, which does not allow a clear and accurate answer to be provided. The context you provided in the figure and following paragraph does not align with the question. Instead, the figure and paragraph seem to refer to historical military operations, which are different from the logistics operations possibly suggested by the question about the delivery of packages. Without additional information or context that directly relates to the question, a definitive answer cannot be provided.
