Jeff, don't mess up the warbird arrival ,it is needed and works well. There may be some of the planes, T34 for example that can comfortably and safely fly 90 knots Ripon -Fisk, but a lot could not. 90knots is short final speed in a Mustang, and base leg speed in a Spitfire. Im sure a B25 or most of the bombers and large transports are faster than that. And you wouldn't want to bring wake turbulence onto the Fisk route for smaller planes to have to fly through. The warbirds seem to be very popular with the public,maybe the most popular segment, don't discourage owners who are spendiing $1000s of their own money to attend Osh without reimbursement except some fuel.
