At my airfield, there is an airplane, at least 13 meters up a tree. I was at my field 3x today, at sun-up, afternoon & sunset. I zoomed my camera on the plane & I'm pretty sure there is no phone number or anything written on it, nor is anything posted to the tree, nor was anyone nearby. If I make a reasonable effort to find the owner and am unavailable to do so, if I get the plane down, would it be wrong for me to claim it? If asking around yields no information,I'm going to post on the tree & around the field "found plane" and have those claiming it describe it. I see it like this: if I find a wallet with money in it, I'll use the ID to return it. If I find cash on the street, no one looking for it, it's mine. I'm sure the original owner wants it back and if I can find that person,I'm happy to return it, but if they don't materialize, they don't answer my postings, and nothing identifying on the plane itself, would I be wrong to claim it? This is NOT a factor, but tomorrow is my birthday and I cannot afford to buy a new plane. That is well outside of the ethical problem, but the timing is serendipitous.
