The "ground flying' was referring to the 3-1/2" gauge track. It was more comfortable to lie down on a long flat car and run your locomotive than to sit upright as the balance was tedious. Because many of us laid down to run, we could go faster. There have been many speed records on that little track! A lot of fun!
