If a plane crashed on the border, then the plane has to have a width of less than the width of the border, which means that the people inside the plane, if they survived, must be even thinner and have a thickness which is less than their shadow, in which case they must be already dead.
Now the border between countries, or the border of a parcel of and area of land, is an imaginary line which cannot cast a shadow even in very bright sunlight.
So for a plane to be able to crash on the border, between two countries or surrounding a parcel of land, it must be able to fly first, and in the case of this riddle it must have passengers on board. The riddle is illogical as a plane with the required dimensions to be able to crash on the border would first of all not be able to fly and secondly it would not be able to carry either a pilot or passengers and as such if the circumstances surrounding this plane that cannot fly or carry a pilot or passengers, it does not exist, it means that the described plane did not exist in the riddle and the riddle is completely illogical. Get my drift.
Now if a plane existed that was three dimensional and the third dimension fitted along the border between the two respective countries or land parcels, then its mass must logically be zero and as such the plane does not exist. So if the plane does not exist, then the survivors of this imaginary plane also do not exist in which case there can be no one to bury.
Now for this riddle to be logical and for survivors to exist, then the plane, that can fly carrying passengers and crew, must crash straddling the respective border in question. Now the survivors when they die who request that they be buried within a pit in the ground that is then filled in to burry them, will be buried within the boundary of the parcel of land designated for such activity. Even in this eventuality we have the same conundrum because of the language used as it suggests that the people are buried within the borders of the said parcel of land.
