I conjecture that a detailed How-To would upset the Department of Defense quite a bit. After all, these remote USAF airbases in the deserts of the Southwest are remote for a reason...
Suppose the U.S. is testing a new secret fighter jet. If you don't know when the new jet will leave the hangar for a test flight, your satellites will be useless. Long-distance photography would perhaps provide some intel. Of course, if the test flights were carried out at night, as it happened while the F-117 was being tested, then photography would not help much,
Do note that when most USAF bases in the Southwest were built, there were no satellites at all, and hence, no spy satellites.
These days you can be arrested if you have a home chemistry lab. Imagine what the government would do to you if you started teaching people how to peek on supposedly secretive military bases.
