I would be cautious with speculation even after labeling it as such. A large number of technical intelligence teams were in Germany prior to it being divided into East and West. Wright Field had issued a list of aircraft it wanted, which was shared with the British. Those aircraft were found at various dispersal points, some near the autobahn which was being used in the final days for takeoffs and landings. Also, all of these aircraft were under camouflage, whether it was tree branches or netting. Allied aerial reconnaissance missions were winding down.

I highly doubt anything was left uncrated. During the war, captured aircraft were being sent to Wright Field for evaluation. At the end of the war, captured documents and German personnel were sent there as well. I have a partial list of these documents. The authors were given as a first initial followed by a last name, such as A. Schwartz. Wright Field consisted of a number of departments of which no comprehensive published history exists. As Phil Butler pointed out in War Prizes, he had to go through a number of file cards which were unproductive along with those that were.

I stumbled across photos of the Lippisch DM-1 being removed from its shipping crate. These were held by NASA.

It would be wrong to assume that these aircraft were all exhibited at special events where Americans took pictures. Some were considered secret and kept from the prying eyes of the new enemy, the Soviet Union.

It is also wrong to assume everything is online. That is definitely not the case when it involves highly specialized subject matter. And in some cases, things are not findable using average search words or in some convenient form. A certain amount of patience is needed when searching through NARA in the U.S. for example. As Phil Butler noted, a lot of material needs to be gone through to get to the desired item. Some material from the war is still classified. This is further complicated by documents completing declassification review but being released in batches with less than descriptive headings. Example: Documents of the U.S. Naval Attache, January to December, 1943. My example may or may not contain any desired information but that requires going over two or more linear feet of documents. The U.S. Navy is often overlooked as a place where aircraft were tested and evaluated.
