I want to know the answer to the following question:
How Many Planes returned from the circumnavigation in 1924?
All the background I'm provided with is that "Two planes made it back, after having covered 27,553 miles (44,342 km) in 175 days, and were greeted on their return September 23, 1924, by a crowd of 200,000 (generously estimated).". Is that enough to answer the question?
