Or the Bf-110 (Me-110); which was a great design when it was first produced, but was slow and awkward by the time it first got into combat. A great plane, actually; but it wasn't exactly a nimble fighter. Or maybe the British WWI B.E. 2c; which was designed specifically to be very stable and easy to control, to aid in observation work; literally flying itself and leaving the pilot time to look around at what was happening on the ground. Unfortunately, it also couldn't get out of the way when German planes started shooting at it. Literally, a flying target. Boy; this could be a very long list. Thanks; Ernie P.
