I've recently become interested in this era of aviation. This is a really good site with a lot of info on the aircraft and aces of WWI. David Ingalls was the US Navy's only ace of that war though techinically by our standards, he was not. The Brits counted shared victories as one victory for all (even if 2 or 6 pilots shared the kill). He has always been credited with 6 though by our rules, it was 3.14. Whatever, good site.
