Sorry to go a bit off topic here, I love air races too, but this one shown, unless my eyes are deceiving me, shows a 4 seat passenger car. Is this one the first to offer a 4 passenger car, I've never seen one with this set up before.
Lagoon has a 4 seat model, and I think it would be awesome if Knott's were to add one of these. I just rode the one at Lagoon this summer and it was amazing. I think the raised platform could work really well if it is themed to a boardwalk/pier and maybe theme the planes to seaplanes.
