We can observe it.
The ISS for one.

I've never heard a pilot, or anyone, say how planes are always in descent, which is very odd. It seems very important, to fly properly,

Clearly, you are not a pilot. Pilots maintain a constant altitude relative to the curving surface of then earth. Satellites in orbit are actually falling at about the same speed as they are traveling forward; this is why they stay in orbit. (This explanation is for the benefit of any child that strays on to that s thread.)
Consider this option ; what if the Earth is not 25K in circum. but , say , it is actually 250K .
When we put satellites up into orbit do they automatically get caught in this double momentum or is there a propulsion system which enables these satellites to sustain the double momentum ?

is it possible you were mistaken ?
PS - sharing your methodology and results - as asked would help

yup... we call them rockets
They get the satellites up to the correct speed to orbit... theres no resistance in a vacuum so once they've reached said speed they generally stay put...
again as i've said in a previous post, they literally fall around the earth using gravity as momentum
