A flight reported near Waverly, Michigan, on September 16, 2026, left conflicting identity details. The aircraft database lists A57AB as a Bombardier Challenger 600, while the transmitted callsign was N57AB. The disagreement leaves the listed registration and aircraft type uncertain for this flight.
