Larry: I think the Stearman was the last biplane used in war for the U.S. and that was only as a trainer. Other countries used biplanes throughout the war notably Italy, the U.K. and the Soviet Union which had very advanced biplanes. I'm sure there were some left over biplanes used here and there for different things but for all intents and purposes the Stearman was the last of its kind and like you said, still used to today.

It's rudder was struck by a torpedo launched by a biplane-the Fairley Swordfish. A fluke strike which resulted in the _B's_ rudder being stuck in a turning position. All the _B_ could do was helplessly steam in a large circle until the Royal Navy caught up with it. I do not recall (does some one?) that the US had a biplane in active service at the start of WWII. Of course, most pilots took their first flights in the ubiquitous Stearman, a biplane that is still flown in present day times. Patrick, ever fly one? 73, lh
