FlightAware.com says the 10-seat Hawker H25 had left Fort Lauderdale on Monday and stopped in St. Paul, Minnesota; Moline, Illinois; and St. Louis before arriving in Cincinnati.
The plane departed from Cincinnati on Tuesday morning and stopped in Dayton before crashing into an apartment building on approach to a small airport in Akron.
A Florida real estate company says seven of its associates were among the nine believed killed in the crash. Nobody on the ground was hurt.
Authorities were back on the scene Wednesday morning to try to recover the bodies.
