Sonex T&Gs, and a Tire Flat on Landing, 12 July 2021

Three good touch and go's at Midwest National, then a final landing in the grass at Roosterville but the tire went flat! It's hard to tell but the plane slowed down faster than normal (I thought maybe the grass was long...), and then you'll see me looking confused and trying to see if I left parts behind me on the runway. Turns out the tire was completely flat by the time I got back to the hangar.
