What legal principle is this? (plane crash on property)

Back in WW2 a B29 (I think) was on a training mission over South Dakota and crashed. The government came in and picked up most of the wreckage but for years locals were still finding parts strewn around.

About 50 years after the incident they did a memorial service at the site.

The particularity clause in the 4th Amendment reads:

“…particularly describing the place to be searched, and the persons or objects to be seized.”

Now, please give me some detail about the “open fields” doctrine and how it applies in this instance, to the alleged exclusion of * Mapp. *

That reminds me of one of those ‘Gotcha!’ questions popular with children. ‘A plane crashes right on the border between two countries. Where do they bury the survivors?’ (The other one I remember is ‘A rooster lays an egg exactly on the top of a steep roof. Which side does the egg roll down?’)

You don’t need a warrant to search an open field so the particularity clause doesn’t apply.

Oh, all right.
