Just a bit of an aside question here. Did US paratroops use British-built gliders for D Day and other assaults/training - either of British or US design?
Yes, the USAAF used UK-built Horsas.

Or did the USA make their own gliders in America and ship (air tow??) them over to Britain for their own use?
The WACO designed CG-4A was the primary US assault glider. A number of forms made more than 13,000 CG-4As. As JDK mentions, one was air towed across the Atlantic, most were shipped in a set of three heavy wooden crates. There are stories that postwar, farmers would buy a brand new surplus glider just for the crates it came in. The crates would be turned into outbuildings or broken down for the lumber.
Whether beacuse of its construction methods or simply because more were produced and some never left the USA, there are a number of survivors on display at various museums, including the National Museum of the USAF. Almost 500 of an advanced model, the CG-15, were also produced.
Fun trivia: Cessna did get an order for CG-4As but subcontracted the entire order to nearby Boeing Wichita. While you'd think Cessna would be well suited to build the metal, wood and fabric gliders, instead they were produced in the aisles of the new B-29 factory while newly hired employees were waiting for B-29 production to begin.
