So here's a good story - original owner sold airplane to buyer who ended up discovering it needed waaaayyyy more mx work than he anticipated and went after the original owner, who tried to tell potential buyer, "sucks to be you, sucker" and only refunded a partial piece or none of the purchase price. The buyer never "took possession" because he didn't want there to be legal record of his ownership of said plane so he could sue previous owner for the money he paid him for a plane that had all sorts of undisclosed maintenance issues with it.
It sat for several years - maybe the previous owner died with everything still in limbo, maybe the potential buyer murdered previous owner and stole his money back, maybe buyer ran out of cash for a lawyer, who knows - but it sat long enough that people kinda forgot about it. Unbeknownst to our OP, however, the airport manager was the best buds of the potential buyer and was holding the plane there until he came back from Tibet to claim it for pennies once the estate settled.
And then along comes OP, and up and claims the abandoned plane and sells it. And for a profit, nonetheless! It's all very insulting, so airport manager fires the OP and the partner for "insider trading". And here we are. Feel free to tweak and change the story to better fit the OP's story as the extra details come trickling in.
