Planes Fly about 30-35,000 ft., and did in the 60s and 70s. I'm a licensed aircraft mechanic. The patents are for an aluminum mixture in the fuel. Also, there were spray nozzles attached to aircraft belonging to Air America, the CIA (Deepstate) airline, which could have sprayed the mixture while in flight. Air temp is relatively the same altitude, and maxes out at 69 degrees Fahrenheit at 37,000 ft.
If no Government would allow this to happen, why would people spend so much time and research and then pay for patents. Here is one such, list of others at bottom.
