ummm an undesired aircraft estate.
let us have a guess....
dear uncle thaddeus, against all advice to the contrary, owned and cherished a Chrislea Super Ace.
You know the super ace, the one aircraft made with a totally different control philosophy where the rocking motion of the yolk controls the rudder etc etc.
ugly as sin to boot.
uncle thad departs the mortal coil and the super ace becomes part of his deceased estate.
problem is that after drawing short straws it eventuates that none among uncle thad's rellies wants a bar of the bloody thing.
so they get together and try to sell the monstrosity.
"for sale, one unwanted aircraft estate...."
apologies to the two people in the world who actually like the Chrislea Super Ace
