There's probably a lot more stuff waiting to be found there. NASA and the Air Force are 'cleaning house', going through old buildings at the Cape Canaveral Air Base, to see and what might be left behind.
Back in the early 1960's, lots of stuff were going on, things like the Boeing Dyna-Soar project ( Dynamic Soarer) a precursor, and in some ways what would have been a better alternative to the Space Shuttle today. The Dyna-Soar was a version of the Sanger-Bendt Silverbird Intercontinental skip-glide rocket bomber that the Nazi's had on the drawing board.
The concept was picked up by Bell Aerospace, which had also recruited Mr. Sanger himself. The plans were upgraded to an orbital platform that could be used as a strike bomber, recon , satellite repair or retrieval and re-supply ship. If the spy program continued, most likely the Dyna-Soar project would have been completed and may have completely altered the course of manned spaceflight that we know about today.
Here is a picture of the 100 % scale model X-20 Dyna Soar. The Pentagon later gave the contract to Boeing, but the project was scrapped in the mid 60's.

Many pilots of the time were the opinion that a fighter pilot in a closed cockpit was an impossible thing, because you should smell the enemy. You could smell them because of the oil they were burning.
