I have access to an Aeronca Chief and the standard stuff (Cessnas and Pipers). I don't believe it's difficult to do formation flying just that it's not the most common circumstance and if we are aiming to get the NTSB and FAA off our butts and keep each other safe, we have bigger issues to focus upon. It's not that I disagree with you, but rather that I was making a point out applicability. I don't generally respond to threads that don't pertain to my interests and that might explain why you saw such a low response.
