TERRETRANE

The most challenging solutions include flights absent daylight and overnight flights. Many overnight flights (less than 12 hours of night) against at higher speeds and against Earth's rotation can be solved with the just-described battery, hydrogen, ammonia, and/or ambilical power. As a final resort, SP-drone aircraft are based on inexpensive construction methods (sheet stock glued together); and so, it is acceptable for the aircraft to spend less time operating between the hours of 12:00 and 5:00 AM. Also, a little contemporary fuel can go a long ways as stop gap for night flight. The bottom line is that proven methods provide market entry positions from which operational logistics and technical solutions will evolve... An approach of applying a volume integral to air's acceleration around an aircraft yields two inherently meaningful results of: 1) during equilibrium flight the net downward "ma" (mass times acceleration) of air is equal to the gravitational force acting on the..
