These guys must have stayed the night in Grand Rapids, MI after their sightseeing tour. I stopped at the GRR airport viewing park since I was super early getting into GR. Glad I did. Seeing an Osprey has been one of my bucket list planes.
Today (Fri) they continued their sightseeing tour. Flew down the Mighty Mississippi from the Hannibal, MO, area; passing the Gateway Arch approx 1630Z. Then they stopped at Spirit of St Louis Airport (KSUS) for lunch & fuel. Departed again 1833Z. Finished up the day at Eisenhower National Airport (KICT) in Wichita.
