@samloonie Yeah, in good (or even just fair) weather, they fit in multiple flights per hour during tourist season.
The Waco is a relatively-modern Second World War era trainer (student pilots often still started in biplanes back then). If you want to see even older, First-World-War-era biplanes still flying ("blip" switches and all),, check out the Great War Flying Museum at Brampton Airport:
