Ya know, I don't know what it costs to rent a plane, but there IS an airport 12 miles away........ Plymouth, Indiana. South Bend Airport is only 30 miles away and can take larger planes. Maybe Brian can take a work plane on a test flight and pack everyone in the back??
I heard a story once of a pilot who landed a plane at the airport. To get the plane up in the air again they had to dismantle it and remove it via truck. That was a big oops.
