Two people are believed to have been aboard the plane that crashed shortly after 2:30 a.m. ET, and it's not clear if they survived, said Joe Rotterdam, an airport operations manager with the Toledo-Lucas County Port Authority.  The aircraft approached Toledo Express Airport as it approached the ground and struck unoccupied vehicles at Bubba's Diesel & Auto Repair operations, just east of the airport, Rotterdam said.
Details of what led to the crash, where the flight originated and what the plane was carrying were not immediately available.
The National Transport S board has heard about the crash, and NTSB investigators are likely to arrive on the scene Wednesday, Rotterdam said.
Because the crash happened away from the airport, the crash will not interfere with other flights there, he said.
