FBO of I69? Airport? F??? B??? Overpass? I just know I am going to feel stupid when you tell me what it is!
I think the box section in the top two pictures has a panel of metal in place that either corroded or came off in some way on the bottom aircraft.
Also, the longer the box opening appears aft
I now feel pretty strongly it is the same plane type.
Fixed Base of Operations. The place where you get gas etc at the airport - Eastern Cincinnati Aviation, Inc.
In this case I69 is Clermont County Airport, Batavia Ohio (like RSW is FAA’s designation for Ft Myers Florida airport, etc.).
It is also the home to Sporty’s Pilot Shop, probably the largest pilot gear catalog company.
They have Sporty’s Academy - a pilot training facility. My son is taking flying lessons - squeezed between football practice and Scouts!
