What does this mean? A flight into RFD from “Near Peoria”? This flight take off from a pumpkin patch in Morton? Some guys yard?
My money is on a giant rubber-band catapult.
But seriously - it’s a position-only flight where there’s no obvious origin airport, just a point where the aircraft was first picked up.
(“Tracking data for this position-only flight is incomplete and potentially inaccurate.”)
The flight likely started VFR and “near Peoria” picked up ATC flight following and/or encountered IFR conditions
