Authorities say a southeastern Michigan plane crash that went unreported for more than four hours left 2 people hurt.
Lenawee County Undersheriff Troy Bevier says the crash occurred about 10 a.m. Friday about a mile from the Lenawee County Airport outside Adrian but went undetected until about 2:20 p.m., when a woman passenger managed to walk to a nearby road and flag down a motorist who called 911.
Bevier says the woman and a man both suffered serious injuries and were transported to a hospital. Their names haven't been released.
Bevier says the single-engine plane broke apart in the crash, with part of it caught in a tree.
He says the cause of the crash wasn't immediately known and the Federal Aviation Administration is sending investigators to the crash site.
