I keep coming back to look at this. I may have to find the pattern or very similar to it. My son got to go up for a ride in one and while sitting in the co-pilot seat, the pilot said "hey Brian, take over for me, I'll be back in a minute" and he got up in left... My son got to fly it... He says it was one of the hi-lites of his flying career. In all his many hours/years of flying though, he has not gotten to go up in a open cockpit bi-plane,,, yet. I have that one up on him, I have gotten to do it twice....
