The F-22 crash site near Harper Lake is now the "Gold Standard" for aircraft crash recovery efforts. I have researched U.S. government crash
retrieval activities extensively, with particular interest in "black projects" from Area 51, Tonopah Test Range, etc. Some clean-up efforts for such
craft have taken as little as a few days, and others up to several weeks. In every case, the responsible government agency had virtually unlimited
resources and very high motivation to clean up the site (national security concerns due to the nature of the particular unacknowledged special access
program). In some cases, declassified documents or testimony from participants clearly state that cleaning up the site was the top priority.
After the F-22 crashed, a five-mile security perimeter was established around the impact crater. Armed security guards were on site 24 hours a day,
seven days a week. Predator drones were used to patrol the airspace, making sure that no unauthorized personnel breached the perimeter. After the
largest debris was collected, a spray fixative (think "liquid wax") was used to capture small debris and particulate matter on the ground. Due to
the large volume of carbon-fiber composite structural material, as well as the usual toxic fuels and lubricants, the debris was treated as hazardous
material. Cleanup crews wore Tyvek overalls and respirators. A decontamination station was established at a temporary Base Camp south of the crash
scene. A very large volume of contaminated soil was excavated in the vicinity of the crater and hauled to a secure landfill. Clean soil was trucked in
to refill the hole. A contractor was then hired to restore the site's original contours and replant native vegetation. Native foliage was plucked
from the surrounding area and planted on the site, but it quickly died due to transplant shock and the fact that nobody made an effort to water it.
The entire cleanup and restoration effort lasted three months. It took longer and was more comprehensive than any crash recovery that I have yet seen
including black projects and nuclear weapon mishaps. Nevertheless, visitors to the site have found numerous pieces of debris from the F-22. This
example is typical, and illustrates why it is unlikely that any "UFO" crash site would ever be truly sanitized.
